Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Upon reflection from a rough surface, amplitude of a reflected ray decreases due to absorption of energy at the surface of reflection. But it is certainly not the reason for the reflection itself to take place.

The statement under "Reason" only explains why reflected rays have a lower energy then the incident rays.
