Answer Key : (c) -

(c)

When the cycle is not pedaled but it is motion (due to previous effort) the wheels move in the direction such that the centre of mass of the wheel moves forward. Rolling friction will act in the opposite direction to the relative motion of the centre of mass of the body with respect to the ground. Therefore the rolling friction will act in the backward direction in both the wheels. The sliding friction will act in the forward direction of the rear wheel during pedaling
