The figure shows the variation of photo current with anode potential for a photo-sensitive surface for three difference radiations. Let l_{a} , l_{b } , and l_{c} be the intensities and f_{a} ,f_{b} , and f_{c} be the frequencies for the curves a , b and c respectively -

Option: 1

f_{a}=f_{b} \ and \ l_{a}\neq l_{b}


Option: 2

f_{a}=f_{b} \ and \ l_{a}=l_{b}


Option: 3

f_{a}=f_{b} \ and \ l_{a}=l_{b}


Option: 4

f_{b}=f_{c} \ and \ l_{b}=l_{c}
