Photons with energy 5 eV are incident on a cathode C in a photoelectric cell. The maximum energy of emitted photoelectrons is 2 eV. When photons of energy 6 eV are incident on C, no photoelectric will reach the anode A, if the stopping potential of A relative to C is

(a) +3 V             (b) +4 V

(c) - 1V              (d) -3 V
