(a) because when cycle is paddled its rear wheel moves in
forward direction but the point where wheel touches the
ground is in backward direction so friction will be in
forward direction in rear wheel but as the front wheel is
not getting any torque so it will be stationary and the
force that rotates it is only frictional force from ground.
so the friction will be in backward direction in front wheel
as only then front wheel will start rotating in the
rotational direction of rear wheal.
