The color of a beam of light does not depends on number of photons or the amplitude of the Wave.
The color depends on the wavelength of the photon absorbed, and the wavelength, frequency and the energy of A photon of light are correlated by the relation as,
E = hv = hc/(wavelength)
So III, IV, V all three are correct so option (d) should be the answer.

Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...
