Energy Release in Fusion vs. Fission

Assertion (A): More energy is released in fusion than fission per nucleon.
Reason (R): More number of nucleons takes part in fusion.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Assertion (A) is true; fusion releases significantly more energy per nucleon than fission. Reason (R) is false; fusion involves lighter nuclei (fewer nucleons) compared to fission.

The higher energy release per nucleon is due to the greater increase in binding energy per nucleon.
