A sphere `S` rolls without slipping moving with a constant speed on a plank `P`. The friction between the upper surface of `P` and the sphere is sufficient to prevent slipping, while the lower surface of `P` is smooth and rest on the ground. Initially `P` is fixed on the ground by a pin `N`. If `N` is suddenly removed

A. `S` will begin to slip on `P`
B. `P` will begin to move backwards
C. The speed of `S` will decrease and its angular velocity with increase
D. There will be no change in the motion of `S` and `P` will still be in rest
