photoelectric effect supports quantum nature of light because...a)there is a minimum frequency below which 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 metal surface is faintly illuminated , the photoelectrons leave the surface immediately . d)electric charge of photoelectrons is quantized.
The First two options are wrong .
And between the last two options , Photo electrons are rather quantized .
It is not necessary that the photoelectrons are emitted immediately when exposed to illumination
So the answer should be (d)
b seems to be more correct....
