When two links of a kinematic pair are not held together mechanically but remain in contact with each other under the action of the force of gravity or some spring action, then such a pair is called an open pair. Eg: cam and follower as shown in figure are in contact due to force of gravity and the forces exerted by the spring.

Yes, ofcourse, Cam and follower is an open pair, because it is not held mechanically. And why it is closed pair.
In the above question, the correct answer is d i.e. Closed Pair not a correct answer A.
i.e.ball and socket joint is a spherical pair.
