Correct answer: (c) Statement-I is correct but statement- II is incorrect
Explanation
- A
Both Statement-I and Statement-II are correct and Statement- II is the correct explanation for Statement-I
Both correct and II explains I. Statement-II is false: power reactors use low-enriched uranium, not 60%.
- B
Both Statement-I and Statement-II are correct and Statement- II is not the correct explanation for Statement-I
Both correct but II does not explain I. II is still false.
- C
Statement-I is correct but statement- II is incorrect
I correct, II incorrect. India is coal-heavy in electricity despite uranium; civil power needs ~3–5% enrichment, not 60%.
- D
Statement-I is incorrect but Statement-II is correct
I incorrect, II correct. Coal still dominates Indian generation.
Summary. Official key is (c). Statement-I is right: most Indian electricity is still coal-fired even though the country has uranium. Statement-II confuses weapons-grade / highly enriched uranium (~90%, or 20%+ HEU) with power-reactor fuel, which is natural or low-enriched uranium (typically under 5%). Sixty per cent is not a civil-power requirement, so II does not explain I.
