AThe superior conchae only
BThe superior and middle conchae
CThe middle conchae only
DThe inferior conchae only
Answer & Solution
Correct answer: D. The inferior conchae only
1. Each lateral wall of the nasal cavity carries superior, middle and inferior conchae.
2. The inferior conchae are separate bones in their own right.
3. The superior and middle conchae are portions of the ethmoid bone, not independent bones.
4. So only the inferior pair qualifies, and every option that names the superior or middle conchae is wrong.
