In both the figures all other factors are same, except that in figure (i) `AB` is rough and `BC` is smooth while in figure (ii) `AB` is smooth and `BC` is rough. In figure (i), if a sphere is released from rest it starts rolling. Now consider the figure (ii), if same sphere is A released from top of the inclined plane, what will be the kinetic energy of the sphere on reaching the bottom:

A

is same in both the cases

B

C

is greater in case (ii)

D

information insufficient
