The correct answer is B. It is possible for the mass of the reactants to be greater than the mass of the products during fusion reactions. The mass of
the products is less than the mass of the reactants because some of the mass
has been converted to energy. Fusion reaction happens when two or more nuclei
combine or collide to form an element with a higher atomic number. In this
process, some of the matter of the fusing nuclei is converted to energy.
