The correct option is (c) PQ

To elaborate: A link is rotating about O. Velocity of point P on link w.r.t. point Q on link will be perpendicular to PQ.

The velocity of any point in mechanism relative to any other point on the mechanism on velocity polygon is represented by the line joining the corresponding points.
