The correct answer is f) glenoid cavity.
The glenoid cavity, also known as the glenoid fossa, is a shallow depression located on the lateral aspect of the scapula. It serves as the socket for the ball-and-socket joint formed with the head of the humerus, allowing for a wide range of motion in the shoulder. This anatomical feature is vital for the stability and function of the shoulder joint, providing both mobility and strength necessary for various arm movements.
