Photoelectric effect supports quantum nature of light because

A

There is minimum frequency of light below which no photoelectrons are emitted

B

The maximum kinetic energy of photoelectrons depends only on the frequency of light and not on its intensity

C

Even when the meal surface is fainlty illuminated the photoelectrons `(if vgt- v(th)` leave the surface immediately

D

electric charge of the photoelectrons is quantized
