Best answer
Right choice is (b) The energy in light comes as small packets

Easy explanation: The conclusion drawn from the experiment of the photoelectric effect is that the energy in light comes as small packets. These small packets of energy are known as quantum of energy or a photon. The magnitude of these is proportional to the frequency of the wave.
