The nuclear fusion results in the liberation of large amount of energy by the conversion of mass to energy. Thus, option B is correct.
The nuclear fusion has been a type of nuclear reaction in which the reaction of the two nuclei results in the nuclei with mass smaller than the reactants. In nuclear reactions, there has been the liberation of large amount of energy.
The energy released in the nuclear fusion has been formed by the conversion of the mass. Since, the formed product has nuclei with the mass smaller than the reactants, the remaining mass of the reactants has been converted to the energy.
Thus, in nuclear fusion, the energy released has been produced from the conversion of mass to energy. Thus, option B is correct.
