**(d)**

The instantaneous axis of rotation will fall on the outside of the sphere. Since incase of pure rotation, the instantaneous axis of rotation will be on the centre. In case of pure rolling, the instantaneous axis of rotation will be on

But if then the instantaneous axis of rotation will fall out of the sphere
