Verified Answer
This question contains Statement-1 and statement-2. Of the four choice...
We know that energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.
Therefore statement (1) is correct.
The second statement is false because for heavy nuclei the binding energy per nucleon decreases with increasing Z and for light nuclei, B.E/nucleon increases with increasing Z.
Therefore statement (1) is correct.
The second statement is false because for heavy nuclei the binding energy per nucleon decreases with increasing Z and for light nuclei, B.E/nucleon increases with increasing Z.

Statement-1: Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.
Statement-2: For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z.
Explanation:
Fission and fusion are two types of nuclear reactions that release energy. Fission involves the splitting of heavy nuclei into lighter nuclei, while fusion involves the combining of light nuclei to form heavier nuclei.
Binding Energy:
The binding energy of a nucleus is the energy required to disassemble it into its constituent protons and neutrons. It is a measure of the stability of the nucleus. The binding energy per nucleon is the binding energy divided by the number of nucleons (protons and neutrons) in the nucleus.
Heavy Nuclei:
For heavy nuclei, such as uranium-235, the binding energy per nucleon increases with increasing atomic number (Z). This means that as the number of protons in the nucleus increases, the binding energy per nucleon increases. This is because the strong nuclear force, which binds the protons and neutrons together, becomes stronger as the number of protons increases. Therefore, more energy is required to break apart the nucleus, resulting in a higher binding energy per nucleon.
Light Nuclei:
For light nuclei, such as hydrogen-1 (a single proton), the binding energy per nucleon decreases with increasing atomic number (Z). This means that as the number of protons in the nucleus increases, the binding energy per nucleon decreases. This is because the electrostatic repulsion between the protons becomes stronger as the number of protons increases. Therefore, less energy is required to break apart the nucleus, resulting in a lower binding energy per nucleon.
Conclusion:
Statement-1 is true as energy is indeed released during fission of heavy nuclei and fusion of light nuclei. Statement-2 is false as it states that the binding energy per nucleon increases with increasing Z for heavy nuclei, which is correct, but it also states that it decreases with increasing Z for light nuclei, which is incorrect. Therefore, the correct answer is option D, Statement-1 is true, Statement-2 is false.
Statement-2: For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z.
