The heat energy released during nuclear fission and fusion is due to the:

1. conversion of stored chemicals into energy
2. conversion of momentum into energy
3. conversion of mass into energy
4. conversion of magnetism into energy

(c) conversion of mass into energy

Explanation

Nuclear fission - It is defined as the splitting of a heavy nucleus into two lighter or daughter nuclei through a nuclear reaction. The heavy nucleus is bombarded with neutrons, which results in the production of a high amount of energy.

Nuclear fusion - It is defined as the combining of two lighter nuclei into a heavier one through a nuclear reaction. Light nuclei have to be heated to extremely high temperature, which results in the production of a relatively high amount of energy.

In both reactions, heat energy is released due to the conversion of mass into energy.
