The Correct Option is C
Solution and Explanation
The correct answer is C) The binding energy is the energy generated when a nucleus is built up from its component nucleons. As a result, the binding energy of the nucleus equals the energy equivalent of the mass defect. Because there are more protons in a heavier nucleus, the internal repulsive forces are stronger, and less energy is required to remove a nucleon from the nucleus, hence the binding energy is lower. As a result, the binding energy is greater for lighter nuclei. The more binding energy there is, the more stable the nucleus.

Nuclei
In the year 1911, Rutherford discovered the atomic nucleus along with his associates. It is already known that every atom is manufactured of positive charge and mass in the form of a nucleus that is concentrated at the center of the atom. More than 99.9% of the mass of an atom is located in the nucleus. Additionally, the size of the atom is of the order of 10-10 m and that of the nucleus is of the order of 10-15 m.
