Photoelectric effect supports quantum nature of light because
(a) there is a minimum frequency of light below which no photo electrons are emitted
(b) the maximum kinetic energy of photo electrons depends only on the frequency of light and not on its intensity
(c ) even when the metal surface is faintly illuminated, the photo electrons leave the surface immediately
(d) electric charge of the photo electrons is quantised

A
