Detailed Solution

A. The stopping potential depends on the energy of incident photon and on the work function of the metal.

B. The saturation current increases as the intensity of incident light increases because number of incoming photons increases.

C. The maximum kinetic energy of a photo electron depends on the energy of incident photon and on the work function of the metal.

D. Photoelectric effect can be explained using particle nature of light.
