Answer
A is True and R is False.
Reason — Synovial fluid is a viscous fluid present in synovial joints. It reduces friction, lubricates the joint, and nourishes the articular cartilage.
The bones of the cranium are connected by immovable joints called sutures, not synovial joints. Sutures are fibrous joints that do not contain synovial fluid.
