Given that a photon of light of wavelength 10,000 $\text{Å}$ has an energy equal to 1.23 eV. When light of wavelength 5000 $\text{Å}$ and intensity I_o falls on a photoelectric cell,
the saturation current is 0.40 x 10^-6 A and the stopping potential is 1.36 V; if the intensity of light is made 4I₀, then the saturation current will become

• A

  $0.40\times 1\mu \mathrm{A}$

• B

  $0.40\times 2\mu \mathrm{A}$

• C

  $0.40\times 4\mu \mathrm{A}$

• D

  $0.40\times 8\mu \mathrm{A}$
