Hint:

When you see a “In contrast” sentence, it usually pairs with the one it contrasts immediately before or after it.

Answer 1

The Correct Option is A

Step 1: The first sentence introduces electricity as the main source. The next detail should be A, describing hydroelectricity and its huge cost.
Step 2: B contrasts atomic power with hydroelectricity in terms of expenditure savings.
Step 3: D then talks about another challenge — coal requirement for electricity.
Step 4: C logically follows, stressing depletion of mineral resources, leading to sentence 6 that promotes atomic plants as a solution.
Sequence: ABDC.
