Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion:
The electromagnetic wave has some energy and this energy of the waves can do work. This work done by a wave can be a result of radiation pressure. Thus, the Assertion is correct.

Reason:
The electromagnetic waves are the result of the magnetic and the electric field present in the medium and therefore, they also have the energy associated with the wave.
In this case, this pressure exerted by the wave is due to the energy possessed by the wave. Therefore, the Assertion and Reason are correct and Reason is also the correct explanation of Assertion.

Option $$(A)$$ is correct.
