Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Since energy released per mass is more in fusion as compared to fission, more energy is released in it. More number of neutrons are released in fission as compared to fusion and hence, more nucleons take part in fission.
