Answer: Option (D) is the correct answer.
Explanation:
Strong nuclear force is defined as the force that is able to hold both the protons and neutrons together in an atomic nucleus.
Since protons have a positive charge and neutrons have no charge. And like charges repel each other. Therefore, protons repel each other due to electrostatic force of repulsion. This force of repulsion is overcome by nuclear binding energy that is also known as strong nuclear force.
This binding energy helps the protons to be bind with each other.
Thus, we can conclude that strong nuclear force will happen inside C.
