Option (c)

The static friction > Sliding Friction > Rolling friction.

The sliding friction is less than static friction because in sliding friction, the interlinking of the two surfaces is for very short time. Thus, the two surfaces could not properly come in contact with each other. But this is not the case for static friction, as the two surfaces in static friction form the contact properly. And, Rolling friction is the friction or drag which opposes the motion when a body rolls. In the rolling motion, the interlinking of the two surfaces is for the least time among all three.
