Options:
  • A Fusion of two nuclei of mass number lying in the range of $100 < \mathrm{A} < 200$ will release energy
  • B Fusion of two nuclei of mass number lying in the range of $51 < \mathrm{A} < 100$ will release energy
  • C Fusion of two nuclei of mass number lying in the range of $1 < \mathrm{A} < 50$ will release energy
  • D Fission of the nucleus of mass number lying in the rang of $100 < A < 200$ will release energy when broken into two fragments

The correct answer is: Fusion of two nuclei of mass number lying in the range of $51 < \mathrm{A} < 100$ will release energy
When two nuclei of mass number lying in the range of $51 < \mathrm{A} < 100$ combined, then a nucleus is formed in the range $100 < \mathrm{A} < 150$ which has high value of specific binding energy. Thus, the fusion of two nuclei of mass number lying in range of $51 < \mathrm{A} < 100$ will release energy.
