Question

Quizplus · Accepted Answer

The reaction described is fusion, which is the process of combining lighter atomic nuclei into heavier ones. Nuclear plants, on the other hand, rely on fission, which is the opposite process of breaking heavier atomic nuclei into lighter ones. Therefore, the best choice is D, which correctly differentiates between fusion and fission.
