Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
A bound system essentially means that the constituents are held together by attractive forces. The potential energy for an attractive force is always negative. But if the constituents had enough kinetic energy, then they would overcome the forces and fly off. But this does not happen because the magnitude of potential energy is greater than kinetic energy. So, both assertion and reason are correct and reason is the correct explanation for assertion.
