Energy transitions and low-carbon paths – UGC NET Question

Statements A, B and C are correct because renewable energy use, efficiency improvements and recognition of fossil fuel lock-in are all central ideas in discussions of low-carbon transitions. Statement D is incorrect since sustainable energy policies usually promote diversification and resilience, not dependence on a single source. Therefore, the only option that includes all three true statements and excludes the false one is A, B and C only.

Option A:
Option A is incorrect because it lists only A and B, leaving out C which is also correct. Lock-in of fossil infrastructure is an important barrier to transitions recognised in energy studies, so ignoring it gives an incomplete picture of the challenges.

Option B:
Option B is correct because it includes all the true statements (A, B and C) and excludes D, which falsely claims sustainable energy policies discourage diversification. This option matches the accepted understanding of low-carbon transitions.

Option C:
Option C is incorrect since it groups C and D together and excludes A and B. Although C is correct, D is wrong because sustainable policies generally encourage a balanced energy mix. Selecting this combination misidentifies the overall set of correct statements.

Option D:
Option D is incorrect because it includes A, C and D but omits B. While A and C are true, D remains false, and excluding B ignores the key role of efficiency as the “first fuel”. A correct answer cannot contain D or leave out B.
