Solution

The maximum kinetic energy of emitted photoelectrons from different metal surfaces depends on:

B. Frequency of the incident light only

This is based on the photoelectric effect, which states that the energy of photoelectrons is dependent on the frequency of the incident light, not its intensity. The nature of the metal surface can affect the threshold frequency (the minimum frequency of light required to emit photoelectrons), but it does not affect the maximum kinetic energy of the emitted photoelectrons.
