Vedclass · Answer

(C) The Assertion is correct because energy is released in nuclear fission of heavy nuclei and nuclear fusion of light nuclei due to the increase in binding energy per nucleon of the product nuclei compared to the reactants.The Reason is incorrect because the binding energy per nucleon curve shows that for heavy nuclei,the binding energy per nucleon decreases with increasing atomic number $Z$ (making them unstable and prone to fission),while for light nuclei,the binding energy per nucleon increases with increasing $Z$ (making them prone to fusion to reach a more stable state).

Assertion: Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.
Reason: For heavy nuclei,binding energy per nucleon increases with increasing $Z$,while for light nuclei,it decreases with increasing $Z$.
