(a,c,d)
After impact, the force of friction will act in a direction opposite to that of the motion. The body will retain its initial angular motion (clockwise). The force of friction will cause linear retardation, reducing 
It will also cause an anticlockwise angular acceleration, which will reduce 
to zero and then introduce anticlockwise 
till rolling without slipping begins. 
will then disappear
