The following graph represents the variation of $ \text{photocurrent} $ with anode potential for a metal surface. Here $ I_1 $, $ I_2 $, and $ I_3 $ represent intensities, and $ \gamma_1 $, $ \gamma_2 $, $ \gamma_3 $ represent frequencies for curves 1, 2, and 3 respectively.

Question

$ \gamma_2 = \gamma_3 $ and $ I_1 = I_3 $

$ \gamma_1 = \gamma_2 $ and $ I_1 \neq I_2 $

$ \gamma_1 = \gamma_3 $ and $ I_1 = I_3 $

$ \gamma_1 = \gamma_2 $ and $ I_1 = I_2 $
