With reference to India’s three-stage nuclear power programme and strategic mineral reserves, consider the following statements: 1 Monazite is a reddish-brown phosphate mineral that serves as a primary source of rare-earth elements and radioactive thorium. 2 India's third stage of nuclear power generation is explicitly engineered to utilize the abundant domestic Thorium-232 reserves by breeding them into fissile Uranium-233. 3 Under current international nuclear trade rules, the Geological Survey of India is completely barred from documenting any new mineral assets inside Karnataka. How many of the statements given above are correct?

With reference to renewable energy transitions and India's "National Biofuel Policy," consider the following statements: 1 First-generation (1G) biofuels are derived from food crops like corn and sugarcane molasses, whereas second-generation (2G) models target non-food lignocellulosic materials. 2 The proposed E85 fuel blend consists of 85% pure bio-ethanol mixed with 15% conventional petrol, requiring specialized flex-fuel engine modifications to prevent fuel-line corrosion. 3 Achieving clean energy benchmarks where renewables meet over 50% of peak electricity demand eliminates the necessity of maintaining grid storage architectures. How many of the statements given above are correct?

With reference to the space hardware and heavy-lift capacities of the Indian Space Research Organisation (ISRO), consider the following statements: 1 Cryogenic rocket engines utilize super-cooled liquid oxygen and liquid hydrogen as propellants to deliver high specific impulse efficiency in upper stages. 2 The CE20 engine is a high-thrust cryogenic engine engineered indigenously by ISRO to power the upper stage of the Launch Vehicle Mark Three (LVM3). 3 Flight-acceptance hot tests are purely digital software code simulations, completely prohibiting any physical engine firing runs at test stands. How many of the statements given above are correct?

Consider the following statements regarding naval architecture and the "Make in India" defense shipbuilding frameworks: 1 The Project 17A frigate design features advanced stealth characteristics, reduced radar signatures, and integrated indigenized weapon configurations. 2 'Mahendragiri' represents the sixth advanced stealth platform built under Project 17A, marking a major milestone for domestic public sector shipyard capabilities. 3 Under international maritime treaties, a "blue-water navy" is strictly limited to operating within shallow, landlocked swimming pools, completely barred from entering open oceans. How many of the statements given above are correct?

Regarding the constitutional distribution of legislative powers over electricity and green energy development under the Seventh Schedule, consider the following statements: 1 "Electricity" is a subject item placed within the Concurrent List entry of the Seventh Schedule, enabling shared center-state legislative synchronization. 2 Formulating massive financial allocation packages (like the World Bank-backed PM Surya Ghar solar program) involves coordinated central policy design to scale up household green grids. 3 State governments possess the absolute autonomous power to unilaterally declare a full conventional war against a foreign lender without consulting the Parliament. How many of the statements given above are correct?
