A photo-cell employs photoelectric effect to convert
(a) Change in the intensity of illumination into a change in photoelectric current
(b) Change in the intensity of illumination into a change in the work function of the photocathode
(c) Change in the frequency of light into a change in the electric current
(d) Change in the frequency of light into a change in electric voltage
