I think the answer is (c).
Because higher pair is where there is line or point contact. If there is partly sliding that means surface contact and where surface contact there will be a lower pair not a higher pair.

D is the correct answer as in the case of gears.

D is the correct answer.
If we consider a cam follower (higher pair) under high speed, then the motion between them is partly turning and partly Sliding.

C is the correct option as higher pair involves point contact.

Answer D is correct:.
Refer to "Relative" mentioned in the question. In pure rolling relative velocity will be zero.

I agree @Ajay Tyagi.

Whatever @Ajay Tyagi said is correct.
Rolling only means one degree of freedom. But higher pair is a two degree of freedom.
Ex: wheel Rolling on a Surface,
The Correct answer is = D.
