Which of the following best describes the insertion of the biceps brachii?

Explanation:
The insertion of the biceps brachii is a two‑part attachment: the tendon anchors to the radial tuberosity, and this same tendon expands into the bicipital aponeurosis that fans out to the forearm fascia. This combination is why the best description includes both the tuberosity of the radius and the aponeurosis. The olecranon is where the triceps attaches, not the biceps, and describing only the radial tuberosity omits the aponeurosis, which is an essential part of how the muscle transmits force and protects underlying structures.
