If cam and follower is an open pair, then why answer is A? Ball and socket joint.

To decide open pair the pair must be held either spring action or due to force of gravity.

Why cam and follower are called open pair? Because they are also called force closed pair.

Correct and is can and follower, because open pair is also called as force closed pair which means two links of pair held together mechanically means of spring or any external force, eg. Can and follower in Ic Engine.
