Answer:
C) mass defect and nuclear binding energy
Explanation:
An atom is composed of three fundamental subatomic particles: protons, neutrons and electrons. While the protons and neutrons reside inside the nucleus of the atom, the electrons revolve around it in fixed orbits.
Nuclear force is the force of attraction between protons and neutrons present in the nucleus. It is made of the nuclear binding energy which hold the nucleons together and the mass defect which represents the change in the masses as the nucleus undergoes radioactive decay.
