Stopping potential for photoelectrons:

The correct answer is Option (3) → depends on both the frequency of the incident light and the nature of the material of cathode

$eV_s=hv-\phi$ [Photoelectric equation]

where,

$v$ - frequency of the incident light

$\phi$ = work function (material property)

$v_s$ = Stopping potential

∴ $v_s$ depends upon both frequency (v) and nature of the material ($\phi$).
