Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Consider a plane perpendicular to the direction of propagation of the electromagnetic wave. If electric charges are present in this plane, they will be set and sustained in motion by the electric and magnetic fields of the electromagnetic wave. The charge thus acquired energy and momentum from the wave. This illustrate the fact that an electromagnetic wave like other waves carries energy and momentum.

So, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
