Which of the Following Best Describes the Source of Energy

Which of the following best describes the source of energy from nuclear reactions?

A) The energy comes from the breaking of chemical bonds to form different molecules.
B) The energy comes from movements of electrons between orbitals.
C) The energy comes from the fact that nuclides are more stable in a nucleus than as individual atomic particles, thus resulting in lower energy and mass than individual particles.
D) The energy comes from the absorption of gamma radiation produced by neutrinos.
E) There is no energy change in nuclear reactions.
