Question

Read the given passages and answer the following question.\ Nuclear energy is released during the transformation of nuclei with less binding energy to nuclei with greater binding energy. Nuclear fission and nuclear fusion are two distinct ways of obtaining energy from nucleus. In nuclear fission, there is splitting of a heavy nucleus $\left({ }_{92}^{235} \mathrm{U}ight.$ or $\left.{ }_{94}^{239} \mathrm{U}ight)$ into two lighter nuclei of comparable masses along with the release of a large amount of energy after bombarded by slow electrons. In nuclear fusion, two lighter nuclei combine to form a heavier nucleus. The union of lighter nuclei into heavier nuclei also lead to a transfer of mass and a consequent liberation of energy.\ For mass defect of $0.3 \%$, the binding energy of 1 kg material is
