• B. superior
• C. proximal
• D. distal

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the anatomical terms used in the question. 'Medial' refers to being closer to the midline of the body, 'superior' means above or higher in position, 'proximal' refers to being closer to the point of attachment or origin, and 'distal' means farther away from the point of attachment or origin.
2. Step 2: Identify the anatomical structures mentioned. The phalanges are the bones in the fingers and toes, while the humerus is the upper arm bone that connects to the shoulder.
3. Step 3: Determine the relationship between the phalanges and the humerus. The phalanges are located farther away from the shoulder (the point of attachment for the humerus) compared to the humerus itself.
4. Step 4: Apply the definition of 'distal.' Since the phalanges are farther away from the point of attachment (the shoulder), they are considered distal to the humerus.
5. Step 5: Confirm that 'distal' is the correct answer based on the anatomical relationship described, as it accurately reflects the position of the phalanges relative to the humerus.
