The graph shows the variation of photocurrent with anode potential for four different radiations. Let $I_{a},I_{b},I_{c}$ and $I_{d}$ are intensities and $f_{a},f_{b},f_{c}$ and $f_{d}$ be the frequencies for the curves $a,b,c$ and d respectively, then

1. A.
   $f_{b} > f_{a},f_{b} = f_{c},I_{c} = I_{d}$
2. B.
   $f_{b} = f_{a},f_{b} > f_{c},I_{c} > I_{d}$
3. C.
   $f_{b} < f_{a},f_{b} < f_{c},I_{c} < I_{d}$
4. D.
   $f_{b} < f_{a},f_{b} > f_{c},I_{c} = I_{d}$
