When monochromatic radiation of intensity $I$ falls on a metal surface, the number of photoelectrons and their maximum kinetic energy are $N$ and $K$ respectively. If the intensity of radiation is $2I$, the number of emitted electrons and their maximum kinetic energy are respectively

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.

In a photoelectric experiment,if the intensity of incident light is doubled and the frequency is kept slightly greater than threshold frequency,then the saturation photoelectric current
