Photoelectric effect supports quantum nature of light because :

A

there is a minimum frequency of light below which no photoelectrons are emitted.

B

the maximum kinetic energy of photo electrons depends only on the frequency of light and not on its intensity.

C

even when the metal surface is faintly illuminated, the photoelectrons leave the surface immediately.

D

electric charge of photoelectrons is quantized.
