Explanation:

Identify anatomical region

The question mentions the "antebrachium," which is the anatomical term for the forearm.

Determine medial bone

In the standard anatomical position, the forearm contains two parallel long bones: the radius and the ulna.

Locate medial vs lateral

The radius is located on the lateral side (thumb side), while the ulna is located on the medial side (pinky side).

Match with options

Since the girl broke the medial bone of her antebrachium, she broke her ulna. This corresponds to option E.

Answer:

• A Her carpal
• B Her metacarpal
• C Her humerus
• D Her radius
• E Her ulna (Correct answer)
