On a photosensitive surface, if the intensity of incident radiation is increased, the stopping potential

Choose the correct option for the given statements:
Statement-$I$: The kinetic energy of photoelectrons emitted by a photosensitive surface depends on the intensity of the incident radiation.
Statement-$II$: In the photoelectric emission process,the maximum kinetic energy of the photoelectrons increases with increasing intensity of the incident light.

The magnitude of saturation photoelectric current depends upon
