Solution

The correct option is C Assertion is correct but Reason is incorrect
The velocity of photoelectron ejected from near the surface is larger than that coming from interior of metal, because for given energy of the incident photon less energy is spent in ejecting the electron near the surface than that from the interior of the surface.Velocity of the ejected electron will not be zero.
