Photoelectric effect supports quantum nature of light because

Question

Photoelectric effect supports quantum nature of light because (A) there is minimum frequency of light below which no photoelectrons are emitted (B) the maximum energy of photoelectron depends only on the frequency of light and not on its intensity (C) photoelectric effect is an instantaneous process (D) all the above choices are correct

The three experimental facts listed under (a), (b) and (c) cannot be explained on the basis of wave theory of light. All these facts support the quantum (photon) nature of light.
