Solution

The correct option is C Does not depend on the frequency of photon but depends only on intensity of incident light
When intensity of incident photon increases number of electrons emitted from the surface increases due to which current increases. Frequency of incident photon only limits the maximum kinetic energy of the photoelectron emitted and so the current is independent of frequency of photon.
