Answer

Brief Explanations:

Nuclear fusion is the process where light - weight nuclei combine to form a heavier nucleus, releasing a large amount of energy. The first option describes nuclear fission. The second option is incorrect as combining nuclei releases energy not absorbs. The third option is also nuclear fission.

Answer:

Nuclei combine to form a heavier nucleus, releasing energy.
