it has muscles

D
None of the above
Explanation: 

Detailed explanation-1: -The ends of the bones are covered with articular cartilage, a hyaline cartilage, and the entire joint is surrounded by an articular capsule composed of connective tissue that allows movement of the joint while resisting dislocation.

Detailed explanation-2: -Introduction. A joint, also known as an articulation, is a location where two or more bones meet. Most joints contain a single articulation. Each articulation contains the names of two bones (or sockets).

Detailed explanation-3: -Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity.

Detailed explanation-4: -Joints hold the skeleton together and support movement. There are two ways to categorize joints. The first is by joint function, also referred to as range of motion. The second way to categorize joints is by the material that holds the bones of the joints together; that is an organization of joints by structure.
