in nuclear fission and fusion the mass defect is

A) the mass of the reactants that break apart.
B) the mass that canot be found inside the nucleus.
C) the mass lost during the reaction that is converted into energy.
D) the mass that is needed to start the fission or fusion reaction.

Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.
