The elbow joint in humans is formed by the articulation of three bones - humerus, radius, and ulna. The humerus bone of the upper arm meets the ulna and radius bones of the forearm to form a hinge joint that allows for flexion and extension of the arm. Therefore, option D, humerus, radius, and ulna, is the correct answer.
