E) is absorbed in the process.

Question

Quizplus · Accepted Answer

In a fusion reaction, two lighter nuclei combine to form a heavier nucleus. The resulting nucleus has a greater binding energy than the original nuclei. This difference in binding energies is released as energy in the form of photons (light) and kinetic energy of the products. Therefore, choice A, "is greater than the binding energy of the original nuclei," is the best choice.
