Answer 1

Answer:

(d)

Explanation:

rolling,sliding ,static are in increasing order of friction.

as we know that, during rolling motion of a body ,the area of contact is very less as compared to sliding body. so, friction is also less in rolling and during state of rest of a body, area of contact is more than all the two.
