electrons and neutrons

Pay attention to the word "nuclear" in nuclear reactions. This word tells us that the nucleus of the atom is affected and involved in nuclear reactions.

The nucleus consists of two different particles, protons and neutrons. Thus, protons and neutrons (the particles of the nucleus) are involved in a nuclear reaction.

Your answer is choice B. Let me know if you need any clarifications, thanks!
