Answer C is correct because higher pairs have point contact for example gears and lower pair have surface contact option d not satisfying the above case.

I think answer is C. Point or line contact between elements of pair is higher pair. Here rolling is point contact which is higher pair.

Answer D is correct:.

Refer to "Relative" mentioned in the question. In pure rolling relative velocity will be zero.

C and D are correct answers because rolling pair is a higher pair. For meshing gear partially sliding and turning.

I think answer is C because there is a point or line contact between two links so it is higher pair.

May answer is C. Because in higher pair in point contact when surface contact in lower pair.

Vineet khandelwal said:   1 decade ago
The answer should be definitely C. No doubt only the rolling motion is having higher pairs.

Varsharani said:   1 decade ago
Answer is C, because for higher pair there is always line contact or point contact.

When pair is contain line and surface contact then pair is said to be higher pair.

How one higher pair is split into the two lower pair with one additional link?
