Statement I is incorrect. Consider that the incoming solar radiation (insolation) at the top of the atmosphere is 100 units. As this energy passes through the atmosphere, a part of it is reflected, scattered and absorbed. About 35 units are reflected back into space before reaching the Earth's surface. Out of these, nearly 27 units are reflected by clouds and around 2 units by snow- and ice-covered regions. This reflected portion is known as the Earth's albedo.

The remaining 65 units are absorbed, with about 14 units absorbed by the atmosphere and 51 units absorbed by the Earth's surface. The Earth's surface then re-emits these 51 units as terrestrial (long-wave) radiation. Of this, only 17 units escape directly to space, while the remaining 34 units are absorbed by the atmosphere. Therefore, the atmosphere receives more heat from terrestrial radiation emitted by the Earth's surface than from direct solar radiation.

Statement II is correct. The long-wave (terrestrial) radiation emitted by the Earth's surface is efficiently absorbed by carbon dioxide (CO₂) and other greenhouse gases present in the atmosphere. These gases are particularly effective absorbers of long-wave radiation, which enables them to retain heat and contribute to the greenhouse effect.

Both statements are true and Statement II correctly explains Statement I.

Regarding Statement I: The troposphere isn't uniform in thickness across the globe — it changes depending on latitude. The layer is thickest above the equator and progressively thinner toward the poles. This happens because of temperature differences between these regions: warmer air is less dense and takes up more vertical space, so it pushes the troposphere's upper boundary higher. Near the poles, colder, denser air keeps the layer compressed and shallow.

Regarding Statement II: Near the equator, sunlight strikes the Earth almost directly for most of the year, delivering intense heat to the surface. This surface heating sets up powerful upward-moving air currents — known as convectional currents. These currents actively carry heat energy to great heights, pushing the troposphere's boundary higher than it would otherwise reach.

Why II explains I: The equatorial bulge in tropospheric thickness isn't just a coincidence of temperature - it is directly caused by these strong convectional currents lifting warm air upward. Since the poles lack this vigorous convective heating (sunlight arrives at a low angle, so heating is weak), their tropospheric layer remains much shallower in comparison. This cause-and-effect relationship is precisely why Statement II is the correct explanation of Statement I, confirming option A as correct.

A volcano is essentially an opening or vent in the Earth's surface through which gases, ash, and molten rock (called lava) are released from beneath the ground. When an eruption occurs, several types of material make their way to the surface: lava flows, pyroclastic material (fragmented rock debris), volcanic bombs (large chunks of ejected rock), along with fine ash and dust. In addition to solid and liquid material, volcanoes also release a mixture of gases, primarily nitrogen compounds and sulphur compounds, along with smaller quantities of chlorine, hydrogen and argon.

Isotherms generally run parallel to latitude lines. However, this pattern doesn't hold perfectly everywhere - the deviation from this expected east-west alignment is more noticeable in January than in July, particularly across the northern hemisphere.

Regarding Statement 1: The northern hemisphere contains a much greater proportion of landmass compared to the southern hemisphere, which is predominantly ocean. Because of this uneven distribution, the influence of continental landmasses and ocean currents on temperature patterns becomes much more noticeable and pronounced in the north. During January, isotherms curve northward over the oceans and bend southward over the continents. This distinctive bending pattern is clearly visible over the North Atlantic Ocean, confirming that this statement is correct.

Regarding Statement 2: This statement is incorrect in its reasoning. The warm ocean currents - specifically the Gulf Stream and the North Atlantic Drift - raise the temperature of the North Atlantic Ocean, causing the isotherms there to curve northward. In contrast, over the landmass of Europe, temperatures drop sharply due to the absence of this moderating oceanic influence, causing the isotherms to bend southward instead. Since the statement misrepresents this relationship, it does not hold up as correct.

Cocoa, being the primary raw material behind chocolate production, plays a major role in the economies of several nations globally. The bulk of the world's cocoa output — around 60% — comes from the African continent. How much cocoa a region produces largely depends on factors like climate conditions, soil quality, and prevailing weather patterns in that area.

Topping the list of cocoa-producing nations is Côte d'Ivoire, which produces approximately 22 lakh tonnes (2.2 million tons) of cocoa annually, making it the world's leading producer. It is followed in ranking by Ghana, Indonesia, Nigeria, and Ecuador.

The Ganga, after passing Prayagraj (Allahabad), continues its course eastward through the Gangetic plains, receiving several major tributaries that originate in the Himalayas. When arranged in order from west to east, these Himalayan tributaries join the Ganga as follows:

1. Gomati — This river joins the Ganga first among these four, merging near Kaithi in Uttar Pradesh. Unlike the others, the Gomati is not a true Himalayan river in origin, but it is grouped here based on its confluence position.

2. Ghaghara — Also known as the Karnali in its upper course through Nepal, the Ghaghara is a major snow-fed Himalayan river that meets the Ganga further east, near Chapra in Bihar. It carries a large volume of water and sediment due to its Himalayan glacial origin.

3. Gandak — Originating in the Nepal Himalayas, the Gandak (called Narayani in Nepal) joins the Ganga near Patna, contributing significantly to the river's flow and sediment load during the monsoon season.

4. Kosi — Known as the "Sorrow of Bihar" due to its tendency to frequently change course and cause devastating floods, the Kosi is the last of these four to join the Ganga, merging near Kursela in Bihar. It originates from the high Himalayas, including parts of Tibet.

Thus, the correct west-to-east sequence of these rivers meeting the Ganga is: Gomati → Ghaghara → Gandak → Kosi, making option B the right answer.

Weathering refers to the gradual breakdown of earth materials brought about by the combined action of weather and climatic elements acting on rocks over time. Broadly, weathering processes fall into three categories: (i) chemical, (ii) physical or mechanical, and (iii) biological.

Regarding Statement I: This statement is correct. Chemical weathering works on rocks by decomposing, dissolving, or breaking them down into finer clastic particles through various chemical reactions. These reactions are driven by oxygen, surface or soil moisture, and other naturally occurring acids. For these chemical processes to proceed efficiently, the simultaneous presence of water, air (containing oxygen and carbon dioxide), and adequate heat is essential — these three elements essentially act as catalysts that speed up the breakdown. Rainwater, in particular, is one of the key natural agents responsible for initiating and sustaining this weathering process.

Regarding Statement II: This statement is also correct. Under normal conditions, rainwater has a pH of roughly 5.6, meaning it is mildly acidic rather than neutral. This natural acidity arises because atmospheric carbon dioxide (CO₂) dissolves into falling raindrops, forming a weak carbonic acid solution. Since this acidic rainwater is what actively reacts with and breaks down rock minerals, Statement II logically supports and explains Statement I.

Regarding Statement III: This statement holds true as well. As raindrops fall through the atmosphere, they gradually become saturated with dissolved oxygen, meaning the oxygen content within rain droplets effectively increases during their descent. Because of this, rainwater doesn't just carry water and carbonic acid — it also delivers dissolved atmospheric oxygen to the rock surfaces it contacts.

Putting it together: Rainfall, therefore, acts as a multi-purpose agent — simultaneously supplying water, dissolved CO₂, and oxygen — all of which work together to drive and accelerate chemical weathering of rocks. This makes intuitive sense when one considers that rock decomposition is essentially a series of chemical reactions, and rain conveniently delivers nearly all the necessary reactive ingredients in a single natural process.

Since both Statement II and Statement III independently provide valid explanations for Statement I, option A is confirmed as the correct answer.

The North Sea is bordered by a total of eight countries: Norway, Scotland, England, France, Belgium, the Netherlands, Germany, and Denmark, all of which have coastlines touching this sea. Interestingly, neither Finland nor Russia shares a border with the North Sea, despite both being northern European nations — their coastlines lie along entirely different water bodies (the Baltic Sea and the Arctic Ocean/Barents Sea, respectively).

The North Sea itself holds considerable significance beyond just its bordering nations — it's an important zone for fishing, shipping routes, and offshore oil and gas extraction, particularly for countries like Norway and the UK.

Row 1 is incorrect: The Narmada River originates from the western edge of the Amarkantak plateau. From its source, the river flows through a rift valley, flanked by the Satpura range on its southern side and the Vindhyan range to its north. As it passes near Jabalpur district, the river cuts through marble rock formations, forming a picturesque gorge and giving rise to the famous Dhuandhar Falls - named for the misty, smoke-like spray it produces.

Row 2 is correct: The Hundru Falls owes its formation to the Subarnarekha River, along whose course it lies. This waterfall is situated along the Ranchi-Purulia Road, within the Chota Nagpur Plateau region - an area known for several such scenic waterfalls formed by rivers descending from the plateau's elevated terrain.

Row 3 is incorrect: Jog Falls, alternatively referred to as Gersoppa Falls, is located in the Shimoga (Shivamogga) district of Karnataka. This dramatic waterfall is formed by the Sharavathi River, which originates in the Western Ghats before making its spectacular plunge - one of India's tallest waterfalls.

Row 1 is incorrect: Block Mountains form when extensive sections of the Earth's crust undergo fracturing and are subsequently displaced vertically relative to one another. The raised segments resulting from this process are known as horsts, while the sunken segments are termed graben. A classic example of this mountain-building style is the Vosges Mountains, which are situated in Europe.

Row 2 is incorrect: The Alps that are situated in Europe are counted among the geologically younger fold mountains, characterized by their jagged, rugged terrain and sharply pointed conical peaks.

Row 3 is correct: The Appalachian Mountains, found in North America, stand out as one of the oldest fold mountain systems on the planet, having undergone extensive erosion over vast geological timescales, which has considerably worn down their once-towering peaks.

Row 4 is correct: The Andes, stretching along the western edge of South America, represent one of the youngest and most active fold mountain ranges globally, still marked by high elevations and ongoing tectonic activity.

Since 2019, a total of six Greenfield airports have become operational across India: Kalaburagi (developed at a cost of ₹175.57 crore), Orvakal in Kurnool (₹187 crore), Sindhudurg (₹520 crore), Itanagar (₹646 crore), Kushinagar (₹448 crore), and Mopa (₹2,870 crore). Among these six, only Kushinagar and Mopa hold the distinction of being international airports.

Regarding Statement 1: This statement is correct. The Donyi Polo Airport in Itanagar holds the distinction of being Arunachal Pradesh's first Greenfield airport. It was constructed across more than 690 acres of land, with a project cost exceeding ₹640 crore. Prime Minister Narendra Modi formally inaugurated this airport in 2022.

Regarding Statement 2: This statement is also correct. The Kushinagar International Airport, another Greenfield project, was inaugurated by PM Modi in October 2021, adding to India's growing network of newly built airports.

Regarding Statement 3: This statement is incorrect. The Vijayawada Airport does not qualify as a Greenfield airport project.

Regarding Statement 1: This statement is correct. Water vapour is classified as a variable gas within the atmosphere, meaning its concentration doesn't remain constant but instead fluctuates depending on location and conditions. One consistent pattern is that its concentration decreases as altitude increases - the higher one goes into the atmosphere, the drier the air tends to become.

Regarding Statement 2: This statement is incorrect. In reality, the concentration of water vapour follows the opposite pattern described — it decreases while moving from the equator toward the poles, rather than increasing. In the warm, humid tropical regions, water vapour can make up as much as four percent of the air by volume, owing to high evaporation rates and warm temperatures that allow air to hold more moisture. In stark contrast, across the cold, arid stretches of desert and polar regions, water vapour content drops to less than one percent, since colder air holds significantly less moisture and these regions generally lack substantial sources of evaporation.

The Marine West Coast climate is typically found poleward of regions experiencing a Mediterranean climate, specifically along the western coastlines of continents. The primary regions exhibiting this climate type include: Northwestern Europe, the west coast of North America (particularly north of California), southern Chile, southeastern Australia, and New Zealand.

Because of the strong maritime influence in these coastal areas, temperatures remain relatively moderate throughout the year - notably, winters here tend to be milder than expected for their corresponding latitude, thanks to the moderating effect of nearby ocean waters. During the summer months, average temperatures generally range between 15°C and 20°C, while winter averages fall somewhere between 4°C and 10°C. Additionally, both the annual temperature range (difference between summer and winter averages) and the daily temperature range (difference between day and night) remain comparatively small, a hallmark of maritime-influenced climates.

As for precipitation, this climate type receives rainfall fairly evenly distributed across all seasons, rather than being concentrated in just one part of the year. The total annual precipitation can vary considerably depending on the specific location, ranging anywhere from 50 cm to as much as 250 cm.

Regarding Statement 1: This statement is correct. The Earth's rotation on its axis has a direct influence on the direction in which wind travels. This deflecting influence is referred to as the Coriolis force. Under its effect, winds get deflected toward the right in the northern hemisphere, while in the southern hemisphere, the deflection occurs toward the left. Notably, the extent of this deflection increases as the wind velocity rises - faster-moving winds experience a stronger deflecting effect.

Regarding Statement 2: This statement is also correct. The strength of the Coriolis force is directly related to latitude - it grows stronger as one moves away from the equator. This force reaches its maximum intensity at the poles, where deflection is most pronounced, while at the equator, the Coriolis force is effectively zero (absent), meaning winds there experience no such deflection.

Options 2 and 4 are correct. On 21st June, the Northern Hemisphere is tilted toward the sun, causing the sun's rays to fall directly overhead on the Tropic of Cancer. As a result of this direct alignment, these regions receive a greater concentration of solar heat compared to other times of the year. At the Tropic of Cancer itself, daylight extends beyond 12 hours, as reflected in the table where the 20° latitude experiences roughly 13h 12m of daylight on this date.

Further north, the North Pole is angled toward the sun during this period, meaning locations situated beyond the Arctic Circle experience uninterrupted daylight for approximately six months — a phenomenon clearly shown in the table, where the 90° latitude records "6 months" of continuous daylight on 21st June.

Since a substantial portion of the Northern Hemisphere is receiving direct sunlight during this time, this period corresponds to summer across regions north of the equator. Consequently, 21st June marks the day with the longest daylight hours and shortest night for these northern locations — a pattern that becomes evident when examining how daylight duration increases progressively with latitude in the table, from 12 hours at the equator to a full six months at the pole.

Option b is correct. The Congo Basin holds the distinction of hosting the world's largest tropical peatlands. Within this region, the peat swamp forests are estimated to store around 29 billion tons of carbon - a quantity roughly comparable to three years' worth of total global greenhouse gas emissions. Beyond just storage, the Basin as a whole actively absorbs close to 1.5 billion tons of carbon dioxide annually, making it a significant carbon sink.

Geographically, this vast basin spans across six nations: Cameroon, the Central African Republic, the Democratic Republic of the Congo, the Republic of Congo, Equatorial Guinea, and Gabon. What makes the Congo Basin particularly significant on a global scale is that it stands as one of the last remaining regions on Earth where carbon absorption exceeds carbon emissions - a rare and increasingly valuable ecological function. Given this role, any potential destruction or degradation of this basin could carry severe and far-reaching consequences for the global climate system, making its conservation a matter of worldwide environmental importance.

Regarding Statement 1: This statement is correct. Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have become widely dispersed throughout the environment, showing up in unexpected places such as drinking water sources, various food items, and even food packaging materials.

Regarding Statement 2: This statement is also correct. Although individual compounds within the PFAS family can vary considerably in their chemical structure and properties, they all share one common feature: a carbon-fluorine bond. This particular bond is known for being exceptionally strong, which is precisely why these substances resist breaking down over time — a characteristic that has earned PFAS the nickname "forever chemicals."

Regarding Statement 3: This statement holds true as well. Due to their chemical stability and their extensive presence across the environment, repeated or prolonged exposure to PFAS results in their gradual accumulation within living organisms over time — a process known as bioaccumulation. Since these compounds don't easily degrade, they tend to build up within biological systems, potentially reaching concerning concentrations over extended periods.

A parasitoid refers to an organism whose offspring develop either on or inside another organism - referred to as the host with this developmental process ultimately proving fatal to the host. Interestingly, parasitoids display a blend of traits found in both predators and parasites, making them a somewhat unique ecological category.

Options 1, 3, and 5 are correct. Organisms falling under the parasitoid category include certain species of wasps, various flies (such as tachinid flies), carabid beetles, and certain types of worms, including gordian worms (also known as horsehair worms).

Option 2 is incorrect. While it's true that some centipedes function as predators in their ecosystems, they do not exhibit the specific developmental relationship that would classify them as parasitoids.

Option 4 is incorrect. Interestingly, termites stand out as an exception among insects — unlike most other insect groups, they have no documented or known parasitoids that target them specifically.

The Fabaceae, also referred to as Leguminosae, is more commonly known as the legume, pea, or bean family - representing a large and agriculturally significant group of flowering plants with considerable economic value worldwide.

Option 1 is correct. The groundnut (peanut) is classified within the pea and bean family, making it a genuine legume. Notably, the groundnut holds a unique distinction as the only nut variety that develops underground, unlike most other nuts which grow above the soil surface.

Option 2 is correct. Horsegram, which also belongs to the Fabaceae family, represents a promising grain legume known for its valuable nutritional content and therapeutic properties. It also demonstrates notably strong resilience to climatic stress, allowing it to thrive even under challenging environmental conditions.

Option 3 is correct. Soybean is classified as a flowering plant (angiosperm), more specifically as a dicot (eudicot), and it too falls under the Fabaceae or pea family classification.

Statement-I is correct. The Indian Flying Fox is categorized under Schedule V of the Wild Life (Protection) Act, 1972. This particular schedule is reserved for species regarded as relatively less vulnerable, permitting their hunting under certain regulated conditions. Generally, Schedule V encompasses species that are either widespread in population, abundant, or sometimes viewed as agricultural or nuisance pests. It's worth noting that although the Indian Flying Fox isn't formally labeled as vermin (a category of species that can be eliminated without any legal restriction), its placement within Schedule V still means it lacks the stronger protective measures granted to species listed under Schedules I through IV.

Statement-II is incorrect. The Indian Flying Fox is classified as a frugivore, meaning its diet predominantly consists of fruits, nectar, and flowers rather than any animal matter. This particular bat species serves a valuable ecological function, actively contributing to processes like seed dispersal and pollination within its habitat. Interestingly, this species is sometimes wrongly confused with vampire bats - a distinctly different category of bat known for feeding on animal blood.

Option c is correct. All three organisms - Cicada, Froghopper and Pond Skater are classified as insects, specifically belonging to the same broad taxonomic order.

Cicadas form a superfamily of insects placed within the order Hemiptera, commonly referred to as the "true bugs." Similarly, froghoppers belonging to the superfamily Cercopoidea represent another group of hemipteran insects, situated within the suborder Auchenorrhyncha. Likewise, the Pond Skater also falls under the order.

Regarding Statement I: This statement is correct. On a commercial scale, chewing gum is manufactured using a synthetic gum base, which unfortunately does not break down naturally in the environment. As a direct consequence, discarded chewing gum residue can rightfully be regarded as a significant environmental pollutant, persisting in ecosystems for extended periods.

Regarding Statement II: This statement is also correct. It may come as a surprise, but chewing gum does contain plastic. Specifically, the component labeled as "gum base" among the listed ingredients is largely composed of polyvinyl acetate - a type of plastic material. Since this substance is inherently non-biodegradable, it tends to persist in the environment for a considerable duration without decomposing. This plastic composition is precisely why chewing gum waste poses such an environmental hazard.

Both statements are therefore correct, with Statement II appropriately explaining Statement I, confirming option A as the correct answer.

Pair 1 is incorrectly matched. The indri is recognized as an endangered species, with its natural habitat restricted exclusively to remote regions of northeastern Madagascar - it is not found anywhere else in the wild.

Pair 2 is incorrectly matched. The elk is a subspecies of the red deer (Cervus elaphus). Geographically, this species is distributed across North America, as well as in the high-altitude mountain regions of Central Asia.

Pair 3 is incorrectly matched. Bonobos inhabit the dense rainforests situated within the Congo Basin region of Africa, making this their natural and exclusive range.

The World Toilet Organization (WTO) is an internationally operating non-profit organization dedicated to enhancing sanitation standards and toilet facilities across the globe.

Statement 1 is incorrect. Despite sharing similarities in name and mission scope, the World Toilet Organization does not function as an agency under the United Nations - it operates independently rather than as part of the UN system.

Statement 2 is correct. The World Toilet Organization serves as the organizing body behind the World Toilet Summit and was also responsible for launching World Toilet Day, which later gained United Nations recognition. The organization established both the World Toilet Day and the World Toilet Summit back in 2001, with the subsequent creation of the World Toilet College following in 2005.

Statement 3 is incorrect. The WTO functions as an international platform that brings together toilet-focused associations, government bodies, academic institutions, various foundations, UN agencies and corporate stakeholders, enabling them to share knowledge and mobilize media and corporate backing in support of promoting clean sanitation practices and public health policies.

Statement 1 is correct. Lions do not follow any fixed breeding season throughout the year. Female lions experience their reproductive cycle continuously, recurring approximately every 16 days, with each estrus phase lasting between four to eight days. Since mating isn't restricted to any particular time of year, female lions are described as being polyestrous in nature.

Statement 2 is correct. Interestingly, cheetahs differ from other members of the big cat family - including lions, tigers, leopards, and jaguars - in that they are incapable of roaring. Instead, when facing a threatening situation, cheetahs tend to growl, while under normal circumstances, their vocal repertoire is generally limited to chirping, purring and meowing.

Statement 3 is incorrect. Both lions and leopards establish and defend their territorial boundaries through a combination of roaring and scent marking. In both species, males and females alike rely on urine marking as a territorial signal, and it's common for a male to scrape the ground immediately after urinating, this behavior helps transfer his scent onto his paws, which then gets spread further as he patrols and moves along his territorial boundaries.

"100 Million Farmers" is an initiative launched under the World Economic Forum (WEF). This platform works toward building regional coalitions, bringing together a mix of stakeholders including public and private sector organizations, non-governmental organizations (NGOs), and various academic institutions. Its core objective centers on accelerating the shift toward net-zero, nature-positive, and more resilient food systems that better support farmers globally.

Beyond this, the initiative also strives to elevate the role of food and farmers, positioning them as central components within the broader global climate and nature agenda. Additionally, it seeks to drive collective, coordinated action aimed at scaling up agricultural practices that are both climate-conscious and nature-friendly, ensuring long-term sustainability in farming systems worldwide.

Distributed energy resources (DER) refer to small-scale, modular technologies used for generating or storing energy, designed to deliver electric power directly at the point of need rather than through centralized grids. These systems generally have a generation capacity below 10 megawatts (MW), and one of their key advantages lies in their flexibility - they can typically be customized in size according to specific requirements and set up on-site at the location where power is needed.

Several technologies fall under the category of distributed energy resources, including:

Mutualism describes a form of ecological interaction in which both participating species derive benefits. Among the most remarkable and evolutionarily intriguing instances of mutualism are those observed within plant-animal relationships. Plants frequently rely on animals to assist with pollinating their flowers and spreading their seeds across the landscape.

A particularly striking illustration of this phenomenon is the relationship between figs and wasps, which are mutually dependent on one another for reproduction - making this an excellent example of co-evolution in action. In numerous fig tree species, there exists a highly specific, one-to-one association with a particular pollinator wasp species. This essentially means that a specific fig species can only be pollinated by its designated 'partner' wasp, with no other wasp species capable of fulfilling this role.

The female wasp utilizes the fig fruit for dual purposes: not only does she use it as a site for laying her eggs, but she also depends on the developing seeds inside the fruit to nourish her growing larvae. As the wasp moves through the fig in search of suitable egg-laying locations, she inadvertently pollinates the fig's inflorescence in the process. In exchange for this pollination service, the fig plant provides a portion of its developing seeds, which serve as a food source for the wasp larvae as they mature.

Item 1 is correct. Monarch butterflies carry toxic compounds within their brightly colored wings, which serve as a natural defense mechanism against predators, with the vivid coloration itself acting as a warning signal.

Item 2 is correct. There are recorded to be more than 1,000 poisonous fish species existing worldwide. Among these, the Reef Stonefish stands out as being widely regarded as the most venomous fish currently known to science.

Item 3 is correct. A substantial number of frog species are recognized for possessing poisonous properties. Within this group, the Golden Poison Frog (Phyllobates terribilis) holds the distinction of being considered the most toxic frog species in existence.

Item 1 is incorrect. The Cashew originally hails from northeastern Brazil, making it a native species to South America rather than India. It was introduced to India by the Portuguese during the late 16th century, meaning it is not indigenous to the subcontinent.

Item 2 is incorrect. Papaya traces its native origins to Central America, though it is now cultivated widely across tropical and warmer subtropical regions globally. Its journey to India involved being brought from the Philippines, passing through Malaysia, before finally reaching India during the latter half of the 16th century - again indicating it is not a native Indian species.

Item 3 is correct. Red Sanders is genuinely endemic to India, being confined to a specific forest belt within Andhra Pradesh. This tree species has unfortunately gained recognition as one of India's most heavily exploited species, facing considerable threats from illegal logging and unauthorized harvesting activities. Following an amendment to the Wildlife (Protection) Act, 1972 enacted in December 2022, Red Sanders has since been placed under Schedule IV of the act.

Statement 1 is incorrect. RTGs (Radioisotope Thermoelectric Generators) are not small-scale fission reactors. Rather than relying on a fission reaction, these devices generate electricity by harnessing the heat released during the natural radioactive decay of a radioisotope - most commonly Plutonium-238. The key distinction lies in the underlying process: within a fission reactor, energy is produced by splitting heavy atomic nuclei apart, whereas an RTG instead derives its energy purely from the decay process of radioactive isotopes, without any nuclear splitting involved. The heat generated through this decay is subsequently transformed into usable electricity via thermocouples, which operate based on the Seebeck effect - a phenomenon where a temperature difference across two distinct conductors or semiconductors generates a measurable voltage.

Statement 2 is correct. RTGs are frequently employed to power spacecraft, proving especially valuable for missions venturing into the outer reaches of the solar system, where sunlight becomes too faint to efficiently power conventional solar panels. Numerous space missions have relied on this technology, including Voyager, Pioneer and New Horizons, along with the Curiosity and Perseverance Mars rovers. The appeal of RTGs lies in their ability to deliver a dependable and long-lasting power supply, a feature that proves essential for the success of deep-space exploration missions.

Statement 3 is correct. Plutonium-238 does serve as the fuel source within RTGs. Although this isotope shares some relation to nuclear materials used in weapons applications, Plutonium-238 specifically stands out as being particularly well-suited for use in RTGs, owing to its comparatively long half-life of roughly 88 years and the substantial heat output it produces throughout its decay process. This isotope typically emerges as a by-product of various nuclear reactions, encompassing both weapons-related processes and the broader production of nuclear fuel.

Statement-I is incorrect. Contrary to what this statement suggests, giant stars have considerably shorter lifespans when compared to dwarf stars. This is because their massive cores consume their available nuclear fuel at a much faster rate, ultimately resulting in a reduced overall lifetime despite their large size.

Statement-II is correct. Owing to their greater mass, giant stars possess hotter and denser core regions. This intensified core environment leads to more vigorous nuclear reactions taking place within them, which in turn accounts for their characteristic high brightness and substantial energy output compared to smaller stars.

Nitric oxide (NO) is naturally synthesized within the human body and serves a vital function in promoting vasodilation - a process that effectively enhances blood flow throughout the circulatory system. The body manufactures this compound starting from the amino acid L-arginine, with the conversion facilitated by the enzyme nitric oxide synthase (NOS). The primary location where NO synthesis takes place is the innermost lining of blood vessels, known as the endothelium, although additional cell types throughout the body also contribute to its overall production.

Functionally, NO acts as a potent vasodilator, working by relaxing the smooth muscle tissue lining arterial walls. This relaxation and subsequent widening of blood vessels leads to improved blood flow, which in turn offers meaningful benefits for overall cardiovascular health.

Beyond its cardiovascular role, nitric oxide additionally functions as a neurotransmitter within the body, playing a part in several neurological processes, including aspects of neuronal activity and learning-related functions.

Radars operate by employing radio waves to detect and pinpoint objects, functioning through the transmission of pulses and subsequent analysis of the reflected signals that bounce back. Through this process, radars are capable of measuring distance, speed and directional movement, making them indispensable across various fields such as aviation, maritime navigation, weather forecasting, and military operations.

Statement 1 is incorrect. At airports, it is X-ray machines and metal detectors - rather than radar-based systems that are employed for security screening purposes. Consequently, radar technology is not utilized for detecting narcotics on passengers or within aircraft.

Statement 2 is correct. Radars find extensive application in monitoring precipitation patterns. In particular, weather radars especially those utilizing Doppler technology play a crucial role in tracking rainfall, measuring its intensity, and assisting in forecasting broader weather patterns.

Statement 3 is correct. Radar systems also prove useful in tracking animal migration, particularly among birds and bats. This technology assists researchers in monitoring flight behaviors and migratory pathways of these creatures across extensive geographical distances.

Fifth-generation fighter jets encompass several major technological advancements developed during the early portion of the 21st century. These aircraft are generally distinguished by features such as stealth capabilities, super cruise (the ability to sustain supersonic speeds without relying on afterburners), advanced avionics systems and networked data fusion that enhances overall situational awareness for pilots. Notable examples of operational fifth-generation fighters include the Lockheed Martin F-22 Raptor, Lockheed Martin F-35 Lightning II, Chengdu J-20, and the Sukhoi Su-57.

Option 1 is incorrect. The Rafale is classified as a fourth-generation (specifically 4.5-generation) fighter jet, developed by France, and therefore does not meet the criteria for fifth-generation classification.

Option 2 is incorrect. Similarly, the MiG-29 also belongs to the fourth-generation category of fighter jets, having been developed by Russia.

Option 3 is incorrect. The Tejas MK-1, despite being an indigenously developed Indian fighter aircraft, is likewise categorized under the fourth generation (4.5-generation) classification rather than the fifth generation.

Hydrogels are essentially water-absorbent, crosslinked polymer networks capable of retaining substantial quantities of water within their structure. These materials find widespread application in the medical field, including uses such as wound dressings, drug delivery systems, and tissue engineering. Their inherent biocompatibility, flexible nature, and ability to respond dynamically to environmental changes collectively make hydrogels particularly valuable across fields like biotechnology and soft robotics.

Statement 1 is correct. Hydrogels are extensively utilized in controlled drug delivery systems, largely because of their capacity to encapsulate medications and subsequently release them gradually over an extended period. This particular application draws heavily on the hydrophilic properties and biological compatibility that hydrogels naturally possess.

Statement 2 is incorrect. While there is ongoing research exploring hydrogel applications within mobile air-conditioning systems particularly regarding evaporative cooling techniques this remains a future possibility rather than a current, established application. At present, hydrogels are not deployed in mobile air-conditioning systems.

Statement 3 is incorrect. In a similar vein, hydrogels are being investigated for potential use in industrial lubricants, where they could theoretically help reduce friction and wear, regulate viscosity, and enhance thermal stability. However, this too remains largely at the exploratory research stage, meaning it would be inaccurate to claim that hydrogels are currently being used for this purpose in practice.

When it comes to Fuel Cell Electric Vehicles (FCEVs) that run on hydrogen, the exhaust output they produce consists purely of water vapor, with no other pollutants involved. Because these vehicles release only water vapor as a byproduct, they qualify as locally emission-free, meaning they don't contribute any harmful pollutants at the point of operation. This characteristic makes FCEVs an important contributor toward achieving cleaner air quality within urban environments, where vehicle emissions typically pose significant air quality concerns.

The term "pumped-storage hydropower" is associated with long-duration energy storage solutions. This technology relies on a system involving two water reservoirs positioned at different elevations, working together to generate electrical power. During operation, water flows downward from the higher reservoir to the lower one — a process known as discharge — passing through a turbine along the way to produce electricity. To reset the system for future use, energy must then be expended to pump the water back upward into the upper reservoir, a stage referred to as recharge.

"Membrane Bioreactors" are typically discussed within the context of wastewater treatment technologies. These systems work by integrating biological treatment processes - which rely on microorganisms to break down contaminants - with membrane filtration techniques, together enabling the efficient removal of pollutants from wastewater. Within this setup, the membranes function as selective barriers, permitting purified water to pass through while simultaneously trapping suspended solids and microorganisms on the other side. Owing to this effectiveness, membrane bioreactors have found widespread application in treating both domestic and industrial wastewater sources.

The term "Collateralized Borrowing and Lending Obligation (CBLO)" is generally examined within the framework of money market instruments. A CBLO essentially represents a contractual arrangement established between a borrower and a lender, wherein the borrower pledges collateral typically in the form of government securities - in return for receiving cash from the lender. Functioning as short-term financial instruments, CBLOs facilitate borrowing and lending activities within a fully collateralized framework, and they are predominantly utilized within India's financial markets.

The Total Fertility Rate (TFR) represents the average number of children that a woman would be expected to have across her entire lifetime, calculated under specific hypothetical conditions. More precisely, it indicates the average number of children a woman would bear by the end of her reproductive years, assuming she experiences the fertility rates applicable during a particular period throughout her entire reproductive lifespan, and further assuming she faces no mortality risk during this time.

Statement 1 is correct. Primary dealers are permitted access to the RBI's liquidity adjustment facility. According to the RBI's own definition of primary dealers: "A non-bank entity applying for permission to undertake PD business shall obtain Certificate of Registration as an NBFC under Section 45-IA of the RBI Act, 1934 from the Department of Non-Banking Supervision, Reserve Bank of India." Based on this framework, non-banking financial companies (NBFCs) operating as primary dealers can utilize the liquidity adjustment facility offered by the Reserve Bank of India.

Statement 2 is correct. Foreign Institutional Investors (FIIs) are granted permission to invest in Government Securities (G-Secs) within the Indian financial market, allowing foreign capital participation in this segment.

Statement 3 is correct. Stock Exchanges operating in India do have the capability to establish dedicated trading platforms specifically for debt instruments, encompassing bonds and other debt securities. This arrangement creates a separate trading mechanism for debt securities, distinct from the trading of equity shares, allowing for more specialized market operations.

All three categories mentioned Insurance Companies, Pension Funds and Retail Investors are permitted to trade in both corporate bonds and government securities within the Indian financial market.

Insurance Companies: These entities constitute significant participants in India's bond market. A substantial share of the premium income they collect from policyholders gets channeled into fixed-income instruments, particularly corporate bonds and government securities, forming a key part of their investment strategy.

Pension Funds: Similarly, pension funds also allocate investments toward corporate bonds and government securities, doing so with the aim of generating steady returns while maintaining financial stability to support future pension payouts. Under current regulations, pension funds are authorized to invest in corporate bonds or securities carrying a rating of 'A' or above (or an equivalent rating on comparable rating scales). However, there exists a specific restriction: investments in bonds rated between 'A' and 'AA-' cannot exceed 10% of the pension fund's overall corporate bond portfolio, ensuring a degree of risk management.

Retail Investors: In recent times, the Indian government has undertaken various initiatives aimed at boosting participation from retail investors within the bond market. As a result, retail investors now have the ability to invest in both corporate bonds and government securities, whether through direct investment channels or indirect investment routes.

Financial instruments are essentially intangible assets that are expected to deliver future economic benefits, typically manifesting as a claim to future cash flows. Such instruments represent tradable assets, embodying either a legal agreement or a contractual right that evidences some form of monetary value or ownership interest within an entity. Generally, financial instruments are bought and sold within financial markets, where their pricing gets determined through the interplay of market forces.

Option 1 is correct. Exchange-Traded Funds (ETFs) qualify as financial instruments that track the performance of an underlying basket of assets which could include stocks, commodities or bonds. These funds are listed and traded on stock exchanges, giving investors the flexibility to buy or sell them just like individual stocks, throughout the trading session.

Option 3 is correct. A currency swap represents a type of financial derivative contract, wherein two parties agree to exchange the principal amounts of loans denominated in different currencies, based on the prevailing exchange rate at the time. This instrument is commonly employed either to hedge against currency-related risks or to secure more favorable interest rates across different currency markets.

Option 2 is incorrect. Motor vehicles, by contrast, do not qualify as financial instruments. Being tangible physical assets primarily used for transportation purposes, they are not traded as financial securities or derivatives within financial markets, distinguishing them fundamentally from true financial instruments.

Pair 1 is incorrect. The storage of agricultural produce does not fall under the secondary sector. While the secondary sector is primarily concerned with processing raw materials, storage essentially constitutes a service-based activity, which properly belongs to the tertiary sector instead.

Pair 2 is correct. Dairy farming is appropriately classified under the primary sector. Since the primary sector revolves around the extraction of raw materials, and dairy farming involves producing milk which itself represents a raw material this pairing holds true.

Pair 3 is incorrect. Mineral exploration does not belong to the tertiary sector. Given that the tertiary sector encompasses service-oriented activities, while mineral exploration involves the process of locating mineral deposits, this activity falls under the primary sector, since it relates to the extraction of raw materials.

Pair 4 is correct. Weaving cloth is correctly associated with the secondary sector. This sector focuses on transforming raw materials into finished products and since weaving involves converting raw materials such as cotton or wool into finished fabric.

Sustainable Aviation Fuel (SAF) refers to a category of fuel designed for use in aircraft, specifically aimed at reducing greenhouse gas emissions associated with aviation. This fuel can be produced from a diverse range of feedstocks, including sources such as corn grain, oil seeds, algae, agricultural residues, forestry residues, wood mill waste, municipal solid waste streams, wet wastes (like manures and wastewater treatment sludge), as well as dedicated energy crops, among various other renewable sources.

Pair 1 is incorrect. While a plough is undoubtedly essential for agricultural production, the concept of working capital specifically refers to items that get consumed during the production process. Since a plough is a durable tool capable of being reused across multiple production cycles, it should instead be classified as fixed capital, not working capital.

Pair 2 is correct. Fixed capital refers to physical assets that remain in use throughout the production process over a relatively extended duration. A computer, being a durable item, fits this description well, as it typically serves in the production of goods or services across several years of use.

Pair 3 is incorrect. The yarn utilized by a weaver should properly be categorized as working capital rather than fixed capital. Working capital encompasses the funds or resources a business relies on for its daily operational needs, which includes purchasing raw materials like yarn, covering wage payments, and meeting other operational expenditures.

Pair 4 is correct. Working capital, broadly speaking, refers to the resources or funds a business allocates toward its routine operations and short-term expenditures - encompassing items like raw materials, inventory, employee wages, and various operational costs. Since petrol gets used up during the production process, it appropriately falls under this working capital classification.

The term that most accurately captures this concept is the "metaverse."

The metaverse describes an interconnected network of three-dimensional virtual worlds, designed to be accessed simultaneously by potentially millions of users at once. Within this digital environment, users have the ability to create as well as own virtual items, adding a layer of personal ownership and interaction to the overall virtual experience.

Statement 1 is incorrect. The RBI has established a minimum capital requirement of ₹5 billion for wholly owned banking subsidiaries. This particular requirement applies uniformly to both new foreign banks looking to establish a subsidiary within India, as well as to existing foreign banks currently operating through a branch presence that wish to transition into a wholly owned subsidiary structure.

Statement 2 is incorrect. According to the Scheme governing the establishment of wholly owned subsidiaries by foreign banks in India, it is required that at least 50 percent of the directors be composed of Indian nationals, NRIs or PIOs, with the additional condition that one-third of the directors must specifically be Indian nationals residing within India.

Statement 1 is correct. CSR (Corporate Social Responsibility) activities are fundamentally designed to benefit society at large, rather than serving the company's own interests. Schedule VII of the Companies Act, 2013 outlines the permissible categories of activities that qualify as CSR initiatives, broadly encompassing areas such as health, sanitation, education, environmental protection, sports, heritage, art and culture, rural development and slum area development.

Statement 2 is incorrect. Under the provisions of the Companies Act, 2013, eligible companies meeting the specified threshold criteria are required to allocate a minimum of 2% of their average net profits, calculated over the preceding three years, toward CSR activities.

Statement I is correct. If the United States were to default on its debt obligations, holders of its treasury bonds would find themselves unable to claim or receive the payments owed to them. Since US government-issued bonds are not secured by any underlying physical asset, a default on these government bonds would directly trigger a genuine default event, leaving bondholders without recourse to any collateral.

Statement II is correct. These treasury bonds derive their backing from the "full faith and credit" of the United States government, rather than being secured by any tangible or hard assets. This means the government's promise and creditworthiness alone serves as the guarantee behind these financial instruments.

Statement-I is correct. In syndicated lending, a collective group of lenders collectively referred to as a syndicate - join forces to extend a single, large loan to a particular borrower. This collaborative lending approach allows the risk tied to the loan to be distributed among all participating lenders within the syndicate, thereby minimizing the exposure and financial risk faced by any individual lender. This syndicated structure proves particularly useful for substantial loan amounts that would be too large for a single lender to manage independently, whether the challenge stems from the sheer size of the loan or the inherent risk associated with it.

Statement-II is incorrect. Syndicated loans can be structured in multiple ways, encompassing both fixed-amount loans (term loans) as well as revolving credit facilities.

Term Loans: These represent fixed-amount loans, wherein the borrower receives a lump-sum disbursement that must subsequently be repaid according to a predetermined schedule over a set repayment period.

Revolving Credit Facilities: These function as flexible credit lines, granting the borrower the ability to draw funds, repay them, and redraw again, all up to a specified credit limit. This structure allows the borrower to access and repay funds repeatedly throughout the duration of the credit facility, offering considerably greater flexibility compared to a standard term loan.

Statement 1 is correct. According to the Reserve Bank's own definition, the Central Bank Digital Currency (CBDC) referred to as e₹ (Digital Rupee) represents legal tender issued by a central bank in a digital format. This CBDC essentially functions as sovereign currency, issued by Central Banks in a manner that remains consistent with their broader monetary policy objectives.

Statement 2 is correct. The Digital Rupee is recorded as a liability on the central bank's balance sheet, reflecting its status as a direct obligation of the issuing authority.

Statement 3 is incorrect. While the Digital Rupee can generally be regarded as a safe store of value, it does not provide any protection against inflation. Much like physical currency, the purchasing power of the digital rupee tends to erode as inflation rises, meaning it offers no special inflation-hedging benefits.

Statement 4 is correct. The Digital Rupee can be freely converted into either commercial bank money or physical cash, ensuring smooth interchangeability between these different forms of currency.

Surviving early Jain and Buddhist texts attribute several names (or epithets) to both Mahavira and Gautama Buddha, each carrying distinct historical and spiritual significance.

Option 1 is incorrect. According to historical accounts, Lord Mahavira was born into a Kshatriya family belonging to the Nadars (Nata-putta) community of Northern India, specifically near Patna (Vaisali), within the Jnatrika or Lichchavi Gotra of the Nyaya Clan, tracing back to the ancient Mahavamsam lineage (associated with Nadars), in the region of Kundagrama. He is also historically referred to by the name "Nayaputta."

Option 2 is correct. Gautama Buddha carries the alternative title "Shakyamuni," which translates to "sage of the Shakyas." This designation stems from "Shakya," representing the name of the tribe or clan to which the Buddha's family originally belonged.

Option 3 is correct. Following his attainment of enlightenment, the Buddha adopted the term "Tathāgata" as a way of referring to himself. This term, sometimes rendered as "nyorai," roughly translates to "one who has arrived from the realm of truth" signifying someone worthy of worship and deserving of offerings, both within the human world and among celestial beings.

Row 1 is incorrect. Chandraketugarh is an archaeological site situated within the state of West Bengal. Based on historical assessments, this site is believed to date back to the 3rd century, placing it within the pre-Mauryan era. Findings from archaeological studies further suggest that this location once served as a significant port city, characterized by the presence of substantial fortification walls.

Row 2 is correct. Inamgaon represents a chalcolithic settlement located in Western India, positioned along the Ghod River, a tributary of the Bhima River within the state of Maharashtra.

Row 3 is correct. The Madankavu urn burial site, classified as a megalithic site, is situated in proximity to Madankavu, a traditional temple that continues to be maintained by local families, located south of Ashtamudi Lake within the state of Kerala.

Row 4 is incorrect. The village of Salihundam is positioned along the banks of the Vamsadhara River in the state of Andhra Pradesh. Archaeological excavations conducted at this site have revealed that it once functioned as an ancient Buddhist settlement. Today, this site remains under the protection of the ASI (Archaeological Survey of India) and contains several notable features, including votive stupas, a mahastupa, along with chaityas and viharas. However, it's worth noting that rock-cut cave shrines were not found at this particular site.

Option a is correct. Krishnadeva Raya maintained cordial and friendly relations with the Portuguese during his reign. Notably, Alphonso de Albuquerque, who served as the Portuguese governor, constructed a fort at Bhatkal, located within the Uttara Kannada district of present-day Karnataka, back in 1510. This construction took place with the explicit permission granted by Krishnadeva Raya, the ruler of the Vijayanagara Empire during the period spanning 1509 to 1529.

Permanent Settlement System:

Designed by John Shore and implemented by Lord Cornwallis in 1793. Local Rajas, Taluqdars, and Chaudharis were made Zamindars, responsible for collecting revenue from villages on behalf of the British State.

Revenue was fixed at 45% of produce, split so that 10/11th went to the Company and 1/11th to the Zamindars. This amount was permanently fixed. The right to collect revenue was hereditary but transferable in case of non-payment, under the "Sunset Clause." If a Zamindar defaulted on payment, his Zamindari rights were confiscated and his property auctioned. Many Zamindars lost their estates this way - some, like Babu Kunwar Singh, later joined the 1857 revolt.

Ryotwari Settlement:

Alexander Read attempted to collect revenue directly from peasants in territories taken from Mysore after the Treaty of Seringapatam (1792), building on the earlier "Risala" system used by Haider Ali and Tipu Sultan. Thomas Munro later refined this system in 1820 as Governor of Madras, since the South lacked large Zamindars, making direct settlement with peasants (ryots) more practical. Peasant fields were surveyed, and revenue fixed for 20-30 year periods.

Under Ryotwari, peasants got no exemption from revenue during bad harvests, only a reduced rent. The Madras Torture Commission Report (1855) recorded torture of peasants for non-payment. Since no British revenue system offered real relief to peasants, Statement 1 is incorrect.

Statement 1 is incorrect. The term "Upanishad" literally translates to "approaching and sitting near," and these texts primarily consist of conversations exchanged between teachers and students. Notably, some Upanishads also incorporate parables as a teaching device. For instance, the story of the "wise beggar" represents a dialogue drawn from one of the most renowned Upanishads - the Chhandogya Upanishad - while the allegory of the two birds finds mention within the Katha Upanishad (Katopanishad).

Statement 2 is correct. The Upanishads were composed as part of the later Vedic literature, dating roughly to the period between 1000 and 600 BC, whereas the Puranas were compiled considerably later, around 200 AD, marking a significant chronological gap between these two categories of texts.

Statement 1 is correct. The International Grains Council (IGC) functions as an intergovernmental organization responsible for overseeing the Grains Trade Convention, with its broader mission centered on fostering cooperation within the global grain trade network. India is counted among the member countries of the IGC.

Statement 2 is incorrect. At present, the IGC's membership comprises only around 30 countries. Importantly, there exists no requirement or mandate under the council's framework stipulating that a country must hold membership in the IGC in order to export or import commodities such as rice and wheat. Countries including Russia, Ukraine, and Afghanistan - despite not being members of the IGC continue to actively engage in the import and export of grains, demonstrating that IGC membership is not a prerequisite for such trade activities.

Option a is incorrect. The Chhau dance, a traditional art form originating from eastern India, was inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity back in 2010.

Option b is incorrect. Durga Puja, often described as the world's largest public art festival, received its inscription on the UNESCO Representative List in the year 2021.

Option c is correct. UNESCO granted inscription to the widely celebrated Gujarati folk dance, Garba, adding it to the Representative List of the Intangible Cultural Heritage of Humanity during its 18th session, held in Kasane, Botswana, spanning 5th to 9th December 2023. With this addition, Garba now stands as India's 15th entry on this prestigious UNESCO list.

Option d is incorrect. The Kumbh Mela, a major festival celebrated on a rotational basis across Allahabad, Haridwar, Ujjain, and Nashik every four years, was inscribed on the UNESCO Representative List in 2017.

The Indian Constitution was framed by the Constituent Assembly of India, a body that came into existence through members elected from the various provincial assemblies, who were themselves chosen by the people of India.

Dr. Sachidanand Sinha, being the oldest member of this assembly, was initially elected as its temporary (or interim) chairman, following a convention drawn from the French practice of appointing the eldest member to preside temporarily. Subsequently, Dr. Rajendra Prasad was elected as the assembly's permanent president.

Meanwhile, Dr. B.R. Ambedkar held the position of chairman of the Drafting Committee, playing a central role in shaping the final text of the Constitution.

Statement 1 is correct. The Government of India Act, 1935 did make provisions for establishing an All-India Federation, intended to bring together both the British Indian provinces and the Princely States under a unified federal structure. However, the actual formation of this federation was made contingent upon a specified number of princely states agreeing to join voluntarily a condition that was never fulfilled, and consequently, this proposed federation never came into existence in practice.

Statement 2 is incorrect. Under the provisions of the Government of India Act, 1935, the subjects designated for administration were categorized into "reserved" and "transferred" subjects. The reserved subjects encompassing areas such as foreign affairs, defense, tribal regions, and ecclesiastical matters were meant to be handled exclusively by the Governor-General, rather than the federal legislature, and this was done based on the advice of executive councilors, not through legislative involvement.

Option a is incorrect. The Kavyalankara represents a treatise on poetics, generally attributed to the scholar Bhamaha.

Option b is incorrect. The Natyashastra stands as an ancient Indian treatise focused on the performing arts, with its authorship attributed to Bharata Muni.

Option c is correct. The Madhyama-vyayoga is counted among the thirteen plays traditionally credited to Bhasa. This particular work takes the form of a one-act play (vyayoga), drawing its narrative from the Mahabharata, with the storyline centering on the reunion of the Pandava brothers.

Option d is incorrect. The Mahabhashya serves as a commentary on Panini's grammatical work, and its authorship is attributed to Patanjali.

A considerable number of Indian monks who journeyed to China during these particular centuries originated from Kashmir. Among this group was Sanghabhuti, recognized as the author of a commentary on the Sarvastivada Vinaya, who is recorded as having been present in China during the period spanning 381 to 384 CE.

Statement 1 is correct. In 2023, UNESCO granted World Heritage status to Shantiniketan, marking its formal entry onto the World Heritage List.

Statement 2 is incorrect. UNESCO recognized Rani-ki-Vav as a World Heritage Site much earlier, specifically in 2014, rather than the year mentioned.

Statement 3 is correct. Alongside Shantiniketan, the Sacred Ensembles of the Hoysalas also earned a spot on UNESCO's World Heritage List during the same year, 2023.

Statement 4 is incorrect. Mahabodhi Temple Complex in Bodhgaya had already achieved World Heritage recognition back in 2002.

Article 368 of the Indian Constitution grants Parliament the authority to exercise its constituent power, allowing it to amend the Constitution through means of addition, variation, or repeal of any constitutional provision. This power, however, must be exercised strictly in accordance with the specific procedure laid down within this article itself, and applies regardless of any other provisions elsewhere in the Constitution. Based on this constitutional provision, points 1, 2, and 3 are confirmed to be correct.

Option 1 is correct. According to figures released by the national statistics bureau, births in Italy fell to an unprecedented historic low, dropping below 400,000 during 2022, as the country's population continued shrinking. Over the past year, Italy recorded more than 12 deaths for every 7 births, with the resident population declining by 179,000, bringing the total down to 58.85 million figures reported by ISTAT in its annual demographic report.

Option 2 is correct. Preliminary government data released showed that the number of babies born in Japan declined for an eighth consecutive year, reaching a fresh record low in 2023, highlighting the significant challenge Japan faces in attempting to curb depopulation trends. Births dropped by 5.1% compared to the previous year, totaling 758,631, while marriages fell by 5.9% to 489,281 marking the first occurrence in 90 years that this figure dipped below 500,000. This trend signals a further anticipated population decline, particularly since births outside marriage remain rare within Japanese society.

Option 3 is incorrect. Contrary to facing a declining population problem, Nigeria is projected to experience substantial population growth rising from over 186 million people in 2016 to an estimated 392 million by 2050, which would position it as the world's fourth most populous nation.

Option 4 is correct. South Korea's fertility rate, already recognized as the lowest globally, continued its steep downward trajectory throughout 2023, as women increasingly prioritizing career growth and weighing the substantial financial burden of raising children opted to either postpone childbirth or forgo having children altogether. Data from Statistics Korea revealed that the average number of children a South Korean woman is expected to have during her reproductive years fell to a record-low 0.72, down from 0.78 the previous year.

Option 5 is incorrect. South Africa's population is projected to increase, growing from 59 million in 2020 to approximately 66 million by 2030, and further reaching 80 million by 2080 indicating sustained population growth rather than decline.

Statement 1 is correct. Article 109 of the Indian Constitution lays down the special procedure applicable specifically to Money Bills, distinguishing their passage from that of ordinary legislation.

Statement 2 is correct. As specified under Article 109(1), a Money Bill cannot be introduced in the Council of States (Rajya Sabha) it must originate exclusively in the Lok Sabha.

Statement 3 is correct. Per Article 109(2), once a Money Bill has been passed by the Lok Sabha, it must be forwarded to the Rajya Sabha for its recommendations. The Rajya Sabha is then required to return the Bill to the Lok Sabha, along with its suggested recommendations, within a period of fourteen days from receiving the Bill. Following this, the Lok Sabha retains the discretion to either accept or reject, in whole or in part, the recommendations put forward by the Rajya Sabha. Additionally, according to Article 109(5), should the Rajya Sabha fail to return the Bill within this fourteen-day window, the Bill is automatically deemed passed by both Houses of Parliament.

Statement 4 is incorrect. Reading Article 109(2) together with Article 109(5), it becomes clear that while the Lok Sabha may consider the recommendations proposed by the Rajya Sabha, it is under no obligation to incorporate or accept any of the suggested amendments.

The correct sequence of equivalent ranks across India's three armed forces is as follows:

Complete List of Equivalent Ranks:

This hierarchical structure demonstrates how each rank level within the Indian Army corresponds to an equivalent designation within both the Indian Navy and the Air Force, maintaining parity in seniority and responsibility across all three branches of the Indian Armed Forces. The ranks marked with an asterisk (*) - namely Field Marshal, Admiral of the Fleet, and Marshal of the Air Force - represent honorary five-star ranks, which are rarely conferred and typically reserved for exceptional distinction.

Following the North Eastern Council (Amendment) Act, 2002, Section 3 of the original 1971 Act underwent substitution, and the amended provisions now define the council's composition as follows:

It's worth noting that while the Home Minister holds the position of ex-officio Chairman of the Council, this role does not count him as a formal member under the composition outlined in Section 3 of the Act his position as Chairman exists separately from the membership structure itself.

Delimitation refers to the process of determining the number of seats as well as fixing the boundaries of territorial constituencies within each State, applicable to both the Lok Sabha and State Legislative Assemblies. The Union government sets up a Delimitation Commission whenever a corresponding Delimitation Act comes into effect. Historically, under the Delimitation Acts of 1952, 1962, 1972 and 2002, such Commissions were constituted on four separate occasions - specifically in 1952, 1963, 1973, and 2002. Notably, no Delimitation Commission was formed following either the 1981 Census or the 1991 Census, marking a gap in this otherwise periodic process.

Options 1, 2, and 3 are correct. The languages Konkani, Manipuri, and Nepali were added to the Eighth Schedule of the Indian Constitution through the 71st Constitutional Amendment Act of 1992, expanding the list of officially recognized languages under this schedule.

Pair 2 is incorrect. C. Rajagopalachari separated from the Congress in 1957, having grown disenchanted with the direction the party was taking at the time. He went on to establish the Swatantra Party in 1959, a party that championed classical liberal ideals and advocated for free enterprise.

Pair 3 is correct. Babu Jagjivan Ram stepped down from both the Cabinet and the Congress Party on 2nd February 1977. Shortly after, he launched his own political party, named the 'Congress for Democracy' (CFD), on 5th February 1977.

Pair 4 is incorrect. Acharya Narendra Dev played a key role in founding the Congress Socialist Party in 1934, which functioned as a radical faction operating within the Indian National Congress. Under the joint leadership of Jayaprakash Narayan and Acharya Narendra Dev, the Congress Socialist Party went on to play a significant role during the Quit India Movement of 1942.

Statement 1 is correct. The Constitution (Seventy-Fourth Amendment) Act, 1992 brought about the introduction of a new Part IXA within the Indian Constitution, specifically addressing matters related to Municipalities, spanning Articles 243P to 243ZG. Within this Part, Article 243W specifically deals with the powers, authority, and responsibilities vested in Municipalities.

Statement 2 is correct. Part XVIII of the Indian Constitution houses the provisions governing emergencies, outlining the framework for handling various types of emergency situations.

Statement 3 is correct. Part XX of the Indian Constitution contains the provisions concerning amendments, laying out the procedures and mechanisms through which the Constitution can be formally amended.

Option a is incorrect. Inter-state trade and commerce falls under Entry 42 of the Union List, as specified in the Seventh Schedule of the Indian Constitution not under the State List as the option suggests.

Option b is incorrect. Similarly, inter-state migration is classified as a subject under the Union List within the Seventh Schedule, rather than being placed under the State List as claimed.

Option c is correct. Inter-state quarantine is listed under the Union List of the Seventh Schedule, confirming its status as a subject falling under central (Union) jurisdiction within the Indian Constitution.

Option d is incorrect. Corporation Tax is categorized under Entry 85 of the Union List, as per the Seventh Schedule again, not under the State List as incorrectly stated.

In the landmark case of Justice K.S. Puttaswamy & Another vs. Union of India and Others, the Supreme Court, in a significant ruling delivered in 2017, unanimously held that privacy constitutes a fundamental right, recognizing it as an intrinsic component of the right to life and personal liberty guaranteed under Article 21, and forming part of the broader freedoms enshrined within Part III of the Constitution. The Bench further clarified that while privacy is a fundamental right, it is not absolute in nature, remaining subject to reasonable restrictions as circumstances may require.

The Chief of Defence Staff (CDS) carries several key responsibilities and functions, including the following:

Statement 2 is incorrect. The CDS does not exercise any form of military command authority, including command over the three individual Service Chiefs. This deliberate exclusion ensures that the CDS can maintain the ability to provide impartial and unbiased advice to the political leadership, free from any conflicting command responsibilities.

Through 'Operation Sadbhavana (Goodwill)', the Indian Army actively engages with local communities residing in remote and far-flung areas, implementing a range of civilian welfare programmes designed to enhance the quality of life for residents across the Union Territory (UT) of Ladakh. This initiative works toward addressing the fundamental needs of these communities. Beyond involving youth in sporting events and facilitating discussions on pressing issues like drug abuse, the Army also regularly conducts medical camps and organizes capacity-building trips for both students and farmers as part of this ongoing operation.

Option a is correct. Canada and the United States share the longest international land border in the world, stretching approximately 8,893 kilometers. This border is effectively divided into two distinct segments: one being the boundary shared between Canada and the continental United States, and the other being the separate stretch shared between the state of Alaska and northern Canada.

Statement 1 is correct. The late Speaker G.M.C. Balayogi initially set up an ad hoc Ethics Committee in the year 2000, which subsequently gained permanent status within the House only in 2015.

Statement 2 is incorrect. Any individual wishing to file a complaint against a Member must do so through another Lok Sabha MP, accompanied by supporting evidence of the alleged misconduct, along with an affidavit affirming that the complaint is not "false, frivolous, or vexatious." However, if the Member concerned files the complaint personally, this affidavit requirement does not apply. Additionally, the Speaker holds the authority to refer any complaint against an MP to the Committee for further examination.

Statement 3 is correct. The Committee does not entertain complaints that are based solely on media reports, nor does it take up matters that are currently sub judice (under judicial consideration).

In September 2023, a historic milestone was achieved when Parliament passed the Women's Reservation Bill, officially titled the "Nari Shakti Vandan Adhiniyam." This Bill aims to reserve one-third of the total seats for women within the Lok Sabha, State Legislative Assemblies, and the Delhi Assembly. The specific allocation of these reserved seats shall be determined by whichever authority is subsequently prescribed by Parliament.

Statement 1 is incorrect. As per the Bill's provisions, the reservation will only come into effect following the publication of a new census and the completion of the delimitation process.

Statement 2 is correct. The reservation of seats for women is designed to automatically expire 15 years after the commencement of this Amendment Act, establishing a built-in sunset provision.

Statement 3 is correct. The Bill further stipulates that one-third of the total seats already reserved for Scheduled Castes and Scheduled Tribes shall specifically be set aside for women belonging to these groups, applicable within both the Lok Sabha and the various state legislative assemblies.

Statement 1 is incorrect. Exercise MITRA SHAKTI-2023 is a joint military exercise conducted between India and Sri Lanka.

Statement 2 is correct. The ninth edition of this joint military exercise, titled "MITRA SHAKTI-2023," commenced in Aundh, Pune, marking the latest installment of this ongoing bilateral engagement.

Statement 3 is correct. The scope of this exercise encompasses synergizing joint responses during counter-terrorist operations. Both participating sides practiced various tactical maneuvers, including raid operations, search and destroy missions, and heliborne operations, among others. Additionally, the exercise curriculum also incorporated elements such as Army Martial Arts Routine (AMAR), combat reflex shooting, and Yoga sessions.

Statement 4 is correct. A total of 15 personnel from the Indian Air Force, alongside five personnel from the Sri Lankan Air Force, took part in this joint exercise.

Prohibition essentially means "to forbid." This particular writ is issued by a higher court directed toward a lower court or tribunal, with its purpose being to prevent the latter from exceeding its jurisdictional limits or assuming authority that it does not legitimately possess. Importantly, the writ of prohibition can only be issued against bodies functioning in a judicial or quasi-judicial capacity.

This writ typically comes into play when a lower court or tribunal either acts without proper jurisdiction, exceeds its designated jurisdictional boundaries, or violates the principles of natural justice, or alternatively, when it infringes upon fundamental rights. Additionally, the writ of prohibition may also be invoked in situations where a lower court or tribunal operates under a law that is itself ultra vires (beyond legal authority).

Statement 1 is incorrect. As per Article 342 of the Indian Constitution, it is the President not the Governor of the state who holds the authority to specify, with respect to any particular State or Union Territory, which communities shall be deemed as Scheduled Tribes in relation to that specific State or Union Territory. This specification is made after due consultation with the state's Governor, though the final authority to notify rests with the President.

Statement 2 is correct. The Supreme Court of India has, through multiple judgments, clarified that a community recognized as a Scheduled Tribe within one particular state does not automatically hold that same status if it resides in a different state, meaning ST classification can vary by state.

Statement 1 is correct. Article 112 of the Constitution stipulates that the President of India shall, for every financial year, ensure that an "annual financial statement" is laid before both Houses of Parliament. In practice, it is the Finance Minister who presents the budget in Parliament, doing so on behalf of the President.

Statement 2 is correct. Article 113 specifies that no demand for a grant shall be made except upon the recommendation of the President, establishing the President's constitutional role in authorizing financial demands before they can be presented to Parliament.

Option d is correct. Both "The India Way" and "Why Bharat Matters" were authored by Subrahmanyam Jaishankar, reflecting his contributions as a writer in addition to his role in diplomacy and foreign policy.

Pair 1 is correct. Argentina has been going through one of its most severe economic crises in recent history, characterized by several significant challenges including high inflation, economic recession, currency devaluation, and mounting debt burdens.

Pair 2 is correct. In Sudan, fighting broke out between the regular national army and a paramilitary force known as the Rapid Support Forces (RSF). This conflict stems directly from an intense power struggle unfolding within the country's military leadership.

Pair 3 is incorrect. Turkey continues to remain an active member of NATO and has not withdrawn or rescinded its membership in the alliance, contrary to what this pairing suggests.

Statement I is correct. The SUMED pipeline functions as a strategic transit route for transporting oil and natural gas originating from the Persian Gulf, ultimately reaching destinations across Europe and North America.

Statement II is correct, and it appropriately explains Statement I. The SUMED pipeline is situated within Egypt, serving to connect the Red Sea with the Mediterranean Sea. This geographical connection is precisely what enables the pipeline to function as a crucial strategic corridor for shipping Persian Gulf oil and natural gas onward to European and North American markets, thereby directly accounting for the strategic significance described in Statement I.

Statement 1 is correct. The Red Sea receives minimal precipitation in any form throughout the year. Across most of the Red Sea's coastline spanning both its eastern and western shores annual rainfall remains below 250 mm, which is why this region is generally classified as desert terrain.

Statement 2 is correct. The Red Sea exchanges water exclusively with the Mediterranean Sea and the Indian Ocean. Notably, unlike the majority of the world's seas, the Red Sea does not receive inflow from any rivers, setting it apart in terms of its hydrological characteristics.

The Environmental Protection Agency's (EPA) national ambient air quality standards established for SO2 are specifically designed to provide protection against exposure to the entire family of sulfur oxides (SOx), not just SO2 alone. The primary contributors to SO2 emissions stem largely from fossil fuel combustion occurring at power plants and various other industrial facilities.

Statement I is correct. The Sahel region has experienced increasing instability alongside a deteriorating security environment. For instance, conflict-related fatalities across these countries rose by more than 40 percent during 2022. This decline in security conditions over the past decade has triggered a significant humanitarian crisis, with over 3 million people having fled violence across Burkina Faso, Mali, and Niger, according to figures from UNHCR.

Statement II is correct, and it appropriately serves as the explanation for Statement I.

This region has also witnessed a notably high frequency of coups d'état, with military juntas presently governing in Mali, Burkina Faso, Niger, Chad, and Sudan. Over the course of the past three years, the African Sahel region has experienced a series of coups across seven countries. Specifically, five military coups occurred in five nations - Mali, Burkina Faso, Guinea, Niger, and Gabon — while two additional countries, Chad and Sudan, underwent what are termed "constitutional coups." For example, Mali experienced two separate coups, occurring in 2020 and 2021. Burkina Faso similarly saw a coup take place in January 2022. During July-August 2023, Niger underwent a military coup, resulting in the removal of its democratically elected President. Collectively, these coups have contributed to security breakdowns and economic setbacks across the region, further fueling the growing instability described in Statement I.

Statement I is incorrect. India does, in fact, import apples from the United States of America. Recently, India made the decision to remove additional duties on the import of eight US products, which included apples among them. During FY 2022-23, apple imports from the USA amounted to a value of US$5.27 million, corresponding to approximately 4,486 tonnes in volume.

Statement II is correct. Within India, Genetically Modified (GM) food can only be imported upon receiving approval from the relevant competent authority. The import of food products more broadly is governed by the Food Safety and Standards Act (FSSAI), 2006. Under this regulatory framework, Indian Customs is permitted to clear food products - including Genetically Modified food items - only after obtaining the necessary approval or No Objection Certificate (NOC) from FSSAI. The Food Safety and Standards Act of 2006 explicitly prohibits the import, manufacture, use, or sale of GM food without securing FSSAI's prior approval.

Statement 1 is correct. During the period when a resolution for the removal of the Lok Sabha Speaker is under consideration, he cannot preside over the sitting of the Lok Sabha at that time. However, he retains the ability to remain present within the House during these proceedings.

Statement 2 is incorrect. While a resolution for his removal is being considered, the Speaker does in fact have the right to speak and participate in the proceedings of the House, contrary to what this statement claims.

Statement 3 is incorrect. During the consideration of a resolution for his removal, the Speaker is entitled to cast his vote in the first instance itself - not merely in situations involving an equality of votes, which is how this statement inaccurately frames the provision.

Statement 1 is correct. When the Lok Sabha undergoes dissolution, any bill that remains pending within the Lok Sabha automatically lapses - this applies regardless of whether the bill originated in the Lok Sabha itself or was transmitted to it by the Rajya Sabha.

Statement 2 is correct. Similarly, upon the dissolution of the Lok Sabha, a bill that has already been passed by the Lok Sabha but remains pending before the Rajya Sabha will also lapse under these circumstances.

Statement 3 is incorrect. Contrary to this statement's claim, when the Lok Sabha is dissolved, a bill does not lapse in situations where the President has already notified the holding of a joint sitting prior to the dissolution of the Lok Sabha - this represents an important exception to the general rule.

Under Article 85(2) of the Constitution of India, the President holds the authority to periodically prorogue the Houses, or either House, of Parliament. This act of terminating a session of the House through a formal Order issued by the President, in accordance with this constitutional provision, is referred to as "prorogation." Importantly, the President exercises this power of prorogation only upon the recommendation of the Prime Minister or the Cabinet - that is, the Council of Ministers. Consequently, Statement 1 is incorrect.

Prorogation typically follows the adjournment sine die of the House's sitting. The time gap between the adjournment sine die and the subsequent prorogation generally spans two to four days. That said, the President also retains the ability to prorogue the House even while it remains in session. Given this, Statement 2 is correct.

Furthermore, the President of India possesses the authority to dissolve the Lok Sabha before the completion of its full term, acting on the advice of the Union Council of Ministers. As such, Statement 3 is also confirmed as correct.

Statement I is correct. The European Parliament has recently granted approval to the Net-Zero Industry Act, an initiative aimed at strengthening the production of net-zero technologies within the European Union.

Statement II is incorrect. The European Union's goal of achieving climate neutrality by 2050 referring to an economy operating with net-zero greenhouse gas emissions forms part of the broader European Green Deal, and this target carries legally binding status.

The Act establishes a target for the European Union to produce 40 percent of its annual requirements for net-zero-emitting technologies by 2030, with this goal being based on national energy and climate plans (NREAPs) that individual member states will be required to develop. Additionally, the Act aspires to capture 15 percent of the global market value associated with such technologies. Ultimately, this legislation seeks to ensure that the bloc manufactures 40% of its solar panels, wind turbines, heat pumps, and other clean technology equipment domestically by the year 2030.

Statement I is incorrect. The ongoing socio-economic and political crisis unfolding in Venezuela is characterized by hyperinflation, along with rising rates of starvation, disease, crime and mortality. This deteriorating situation has triggered large-scale emigration from the country. The crisis is widely regarded as, by a considerable margin, the worst economic downturn in Venezuela's history. According to the national Living Conditions Survey (ENCOVI), by 2021, as much as 94.5% of the population was living in poverty, measured on the basis of income levels. Among this group, 76.6% were found to be living in conditions of extreme poverty.

Statement II is correct. Venezuela currently holds the distinction of having the largest proven oil reserves of any country in the world, with estimates placing these reserves at approximately 300 billion barrels of oil.

Statement 1 is correct. The Digital India Land Records Modernization Programme, previously known as the National Land Record Modernization Programme, underwent a revamp and was converted into a Central Sector Scheme, effective from 1st April 2016, with 100% funding provided by the Central Government.

Statement 2 is correct. The key components of this programme include the following:

(i) Establishment of Modern Record Rooms
(ii) Conducting survey and re-survey activities
(iii) Data entry and re-entry processes
(iv) Digitization of cadastral maps, FMBs, and Tippans
(v) Setting up State Level Data Centres
(vi) Computerizing the registration process
(vii) Establishing the DILRMP Cell
(viii) Creating a PMU (Project Management Unit)
(ix) Conducting evaluation studies, IEC activities, and training
(x) Developing Core GIS/software applications

Statement 3 is correct. Among the innovative initiatives launched under the Digital India Land Records Modernization Programme is the transliteration of land records into all languages listed under Schedule VIII, across all States and Union Territories. To overcome the challenge posed by linguistic barriers within land governance, the Government, with technical assistance from the Centre for Development of Advanced Computing (C-DAC), Pune, has launched an initiative to transliterate the Records of Rights - originally available in local languages - into any of the 22 Schedule VIII languages recognized under the Constitution.

The Pradhan Mantri Surakshit Matritva Abhiyan was launched by the Ministry of Health & Family Welfare (MoHFW), under the Government of India. This programme aims to deliver assured, comprehensive, and quality antenatal care, provided free of cost, on a universal basis to all pregnant women across the country.

Statement 1 is incorrect. Under this campaign, a minimum package of antenatal care services is designated to be provided to beneficiaries on the 9th day of every month, specifically targeting women in their 2nd and 3rd trimesters of pregnancy. The programme's objective is to reach out to all pregnant women falling within these trimester categories. These services are made available through Primary Health Centers, Community Health Centers, Rural Hospitals, as well as Sub-District Hospitals, District Hospitals, and Medical College Hospitals.

However, it's important to note that this scheme does not extend to guaranteeing any form of six-month post-delivery care, contrary to what this statement implies.

Statement 2 is correct. The programme additionally encourages active participation from private practitioners on a voluntary basis. Obstetricians and physicians from the private sector, along with retired OBGYN specialists, are invited to offer their voluntary services at designated public health facilities, specifically on the 9th of every month.

To offer old-age protection to workers within the unorganised sector, the Government of India introduced the Pradhan Mantri Shram Yogi Maan-dhan Yojana (PM-SYM) back in 2019. The scheme's fund management is handled by the Life Insurance Corporation of India.

This particular scheme functions as a voluntary and co-contributory pension programme.

Statement 1 is incorrect. Eligibility for this scheme extends to workers falling within the age group of 18-40 years, provided their monthly income does not exceed Rs. 15,000.

Statement 2 is correct. Under this scheme's structure, 50% of the monthly contribution — which ranges between Rs. 55 and Rs. 200, depending on the beneficiary's entry age — is payable by the beneficiary themselves, while an equal matching contribution is provided by the Central Government.

Statement 3 is correct. The scheme's objective is to ensure a monthly pension of Rs. 3,000 becomes available to unorganised sector workers once they reach the age of 60.

Statement 4 is incorrect. In the event of the beneficiary's death, it is the spouse who becomes entitled to receive 50% of the pension as a family pension — however, this family pension provision applies exclusively to the spouse, and this statement's framing misrepresents this specific detail.
