Solution

The correct options are
A A radiation with any frequency will cause photoelectric effect.
B Maximum kinetic energy of photoelectrons will depend on the intensity of radiation.
C Wave theory predicts appreciable time lag with less intense radiation.
If light is seen as a wave, then a light with low frequency can also cause photoelectric effect after a certain amount of time and more the intensity, more will be the force exerted on surface electrons by the electric field and hence the kinetic energy of electrons ejected will be more.
