Explanation:

To solve this, we recall the anatomical regions: The cephalic region (head) includes the facial region (face), and the facial region includes the oral region (mouth area). So we analyze each option:

• Option A: Oral is part of facial, facial part of cephalic. This matches the hierarchy (oral ⊂ facial ⊂ cephalic).
• Option B: Cephalic can't be part of facial (cephalic is larger, includes facial). Incorrect.
• Option C: Cephalic can't be part of facial (cephalic is larger). Incorrect.
• Option D: Facial can't be part of oral (oral is smaller, part of facial). Incorrect.

Answer:

A. The oral region is part of the facial region, and the facial region is part of the cephalic region
