The synovial membrane is the membrane that lines the articular surfaces of the bones of the synovial joint. Its secretes a watery fluid that lubricates and cushions the joint. It reduces the friction during movement.

Tendon is a cord of strong fibrous collagen tissue that connects muscles to bones and doesn't secrete any fluid. 
The ligament is a band of flexible fibrous connective tissue that connects bone to bone and doesn't secret any fluid. 
Cartilage is a tough and flexible material that acts as a cushion between the bones of joints and doesn't secret any fluid. 
So the correct option is D.
