Explanation:

True anatomic joints have a synovial cavity, articular cartilage, and a joint capsule. The acromioclavicular, glenohumeral, and sternoclavicular joints are all synovial (true) joints of the shoulder complex. The scapulocostal joint is a functional (non-anatomic) joint, referring to the sliding relationship between the scapula and the ribcage without the structure of a true joint.

B. Scapulocostal joint
