Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In photoelectric effect, the photon falling on some matter is absorbed by the matter and its energy is transferred to an electron of the matter. In X-ray production, photons are produced which get energy from energetic electrons ionising the inner shells of the target which in turn cause a cascade of emission lines.
