Fusion is the process of joining two light nuclei to form a heavier one. High pressure and high temperatures are used to make this happen. Tremendous energy is released when the fusion takes place. Answers B, C,D, and E are all examples of artificial transmutation or bombardment of an element by a neutron or alpha particle. Only answer A shows two light elements combining.
