Question

Directions: For the Assertion (A) and Reason (R) given below, choose the correct alternative:
Assertion (A): Nuclear fusion is used to generate electricity.
Reason (R): Nuclear power is not used because it cannot be controlled.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true but (R) is false
• D. Both (A) and (R) are false

Hint:

Nuclear fission and fusion are different. Fission is currently used in power plants, while fusion is still in experimental stages. Read questions carefully to distinguish between the two.

Answer 1

The Correct Option is D

Assertion (A) is false because currently, nuclear fusion is not used commercially to generate electricity. Instead, nuclear fission is used in nuclear power plants, as controlled fusion is still under research and not yet practical for commercial power generation.
Reason (R) is also false because nuclear power (fission-based) is used, and it can be controlled effectively — that’s how nuclear reactors work. Hence, the reason is also incorrect.
So, both (A) and (R) are false.
