The correct option is B Cartilaginous joint
Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline) and allow very little movement than the highly mobile synovial joint.
A synovial joint is also known as diarthrosis. In this type, the joining bones are surrounded by a fibrous capsule making the joint space a cavity. Fibrous capsule is continuous with the periosteum of joining bones and is lined by a synovial membrane. The cavity is filled with a viscous fluid, synovial fluid, which provides lubrication of joints. The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints.
