A thin ring of mass 2kg and radius 0.5 m is rolling without slipping on a horizontal plane with velocity `1m/s`. A small ball of mass 0.1kg, moving with velocity `20 m/s` in the opposite direction hits the ring at a height of 0.75m and goes vertically up with velocity `10m/s`. Immediately after the collision

Options

A. the ring has pure rotation about its stationary C. M.
B. the ring comes to a complete stop.
C. friction between the ring and the ground is to the left.
D. There is no friction between the ring and the ground
