Solution
The correct option is C Larger than those coming from the interior of the metal The velocity of electrons ejected from near the surface will be larger than those coming from the interior of the metal because the electrons in the interior goes under collision while coming out. So, they lost some kinetic energy into the collision. So, they come out with less velocity.
