Photoelectric effect supports quantum nature of light because

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

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

even when the metal surface is faintly illuminated (with frequency more than the threshold frequency ) the photoelectrons leave the surface immediately

electric charge of the photoelectrons is quantized

Assertion : Photoelectric effect supports the quantum nature of light. Reason : Photoelectric emission is instantaneous.

Assertion: Photoelectric effect supports the quantum nature of light. Reason : Electric charge of photoelectrons is quantised.

In photoelectric effect

Statement-1 : Photoelectric effect supports the particle nature of light. That means light is not a wave in this case. Statement-2 : The particle nature and the wave nature of light coexist, what we feel is the nature that is dominating at a particular situation.

Assertion : The threshold frequency of photoelectric effect supports the particle nature of light. Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.
