In a nuclear fusion reaction, the mass of the reactants is the mass of the products.

a) less than
b) more than
c) the same as

Nuclear fusion reaction is a reaction in which two or more atomic nuclei come close enough and form one or more different atomic nuclei and subatomic particles (neutrons or protons). During the nuclear fusion reaction a huge amount of energy is released. A fraction of the mass of the reactants is converted into energy.According to this in a nuclear fusion reaction, the mass of the reactants is more than the mass of the products.
