The figure shows the variation of photo current with anode potential for a photo sensitive surface for three different radiations. Let I , I, and I be the intensities and f, f, and f be the frequencies for the curve a, b and c respectively.
A. fa = fb and Ia ≠ Ib
B. fa = fc and Ia = Ic
C. fa = fb and Ia = Ib
D. fa ≠ fb and Ia = Ib
