Solution

The correct option is B If both assertion and reason are true and reason is not the correct explanation of assertion.
The intensity pattern of interference and diffraction are not the same. In interference, Intensity remains constant, and intensity is decreasing in diffraction.
Interference:- It is a superposition of two waves starting from the two different wavefronts.
Diffraction:- It is a superposition of two waves starting from the different portions of the same wavefront.
Hence, Both assertions and reasons are true but the reason is not the correct explanation of assertion.
The correct option is B.
