Solution

The correct option is C Total K.E. on the ground is mgh & ratio of $K E_{t r a n s}$ & $K E_{r o t a t i v e}$ depends upon shape of the body
Since no slipping, $W_{f r i c t i o n} = 0$ & total mechanical energy is conserved. So, it is equal to intial P.E. which is mgh. This distributes between rotational and translational K.E.
