Vedclass · Answer

(C) The Assertion is correct: Energy is released in nuclear fission of heavy nuclei and nuclear fusion of light nuclei because the product nuclei are more stable (have higher binding energy per nucleon) than the parent nuclei.The Reason is incorrect: According to the binding energy curve,for heavy nuclei (mass number $A > 170$),the binding energy per nucleon decreases as $Z$ (or $A$) increases. For light nuclei $(A Since the Assertion is correct but the Reason is incorrect,the correct option is $C$.

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 $Z$.
