Solution

The correct option is A depends on the work function for the metal
Kinetic energy of the photo electrons emitted $K . E = h ν - ϕ$
where $ν$ is the frequency of incident light and $ϕ$ is the work function of metal.
So, more the work function of metal lesser is the kinetic energy of photo electrons emitted.

Q. When light of sufficiently high frequency is incident on a metallic surface, electrons are emitted from the metallic surface. This phenomenon is called photoelectric emission. Kinetic energy of the emitted photoelectrons depends on the wavelength of incident light and is independent of the intensity of light. Number of emitted photoelectrons depends on intensity.

Wavelength of a continuous X-ray depends on potential difference across the tube. Wavelength of characteristic X-ray depends on the atomic number. If potential difference across the tube is increased then:
