Detailed Solution

By observing the graph we can say that:

Beam A has the highest rate of photoelectric emission as the saturation photocurrent is highest for A.

Beam B has highest frequency and photoelectrons ejected by beam B have the highest momentum as the stopping potential is highest for B.

Beam C has longest wavelength as the stopping potential is lowest for C.
