What is photoelectric effect?

Photoelectric effect exp. Observations

The photoelectric effect was crucial in the development of modern physics because it demonstrated theSelect one:a.wave nature of the electron.b.localization of most of the mass of an atom in the nucleus.c.wave nature of light.d.particle nature of light.e.validity of the special theory of relativity.

Please provide a detailed explanation of the physical significance of the I-Vcurve in the photoelectric effect.
