• A. Scapula
• B. Radius
• C. Ulna
• D. Humerus

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the anatomical location described in the question. The lateral aspect of the forearm refers to the side of the forearm that is farther from the midline of the body when in the anatomical position (palms facing forward).
2. Step 2: Recall the bones of the forearm. The forearm contains two primary bones: the radius and the ulna. The radius is located on the lateral side, while the ulna is on the medial side.
3. Step 3: Eliminate incorrect options based on their anatomical locations. The scapula is a shoulder blade and not part of the forearm. The humerus is the upper arm bone, not part of the forearm.
4. Step 4: Confirm that the radius is the correct answer. The radius extends from the elbow to the wrist on the lateral side of the forearm, making it the bone described in the question.
5. Step 5: Reinforce the concept by visualizing or referencing an anatomical diagram of the forearm to see the radius and ulna in their respective positions.
