Which of the following graphs represents the variation of photoelectric current with the property of light shown on the $x-$axis?

One milliwatt of light of wavelength $4560 \ \mathring{A}$ is incident on a cesium surface of work function $1.9 \ eV$. Given that the quantum efficiency of photoelectric emission is $0.5\%$. Planck's constant $h = 6.62 \times 10^{-34} \ J \cdot s$,velocity of light $c = 3 \times 10^8 \ m/s$,the corresponding photoelectric current is:

"With increase in frequency of light incident, number of electrons emitted increase" - True or false?

Light of wavelength $4000 \ \mathring A$ is incident on a sodium surface,where the threshold wavelength for photoemission is $5420 \ \mathring A$. The work function of sodium is ............ $eV$.

If the intensity of incident radiation in a photocell 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.
