Solution

The correct option is A A and B will have different intensities while B and C will have different frequencies.
Clearly when no anode potential is applied, A and B have different intensities(their intersection on I-axis).
Intersection of these curve with V-axis indicates the work potential.
B and C have different work potentials, thus different frequencies.
