Maxill(o) designates which bone?

Explanation:
Maxill(o) points to the upper jaw bone. The maxilla is the bone that forms the upper jaw and holds the upper teeth, and the term appears in anatomy as maxill-/maxillo- in phrases like maxillofacial region. That’s why this root designates the upper jaw bone. The other options refer to unrelated things—breast tissue is mammary, and destruction would be described by different roots—while the lower jaw bone is the mandible, not the maxilla.
