Solution

The correct option is B Amount of photoelectric current
Current in photo electric effect is directly proportionalto the intensity of the incident light. work function, stopping potential, maximum kinetic energy are independent of intensity of incident light, they depend on the frequency, wavelength of the incident light and material of the metal.
