Text Solution

Verified by Experts
The correct answer is:
C

The maximum number of photoelectrons emitted (i.e., saturation current) depends mainly on the intensity of incident light (more photons → more electrons) and also on the nature of the cathode (its quantum efficiency).
However, it is independent of frequency, as long as the frequency is above the threshold frequency. Frequency affects the energy of electrons, not their number.
