Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The electrostatic force is a conservative force i.e., the total energy of the system (potential energy + kinetic energy) remains same and it act in the direction of decreasing the potential energy.
So, when two unlike charges get closer due to electrostatic force of attraction, the potential energy decreases.
Thus, both assertion and reason are true and reason is correct explanation of the assertion.
