A16 to 20
B6 to 10
C30 to 36
D40 to 50
Answer & Solution
Correct answer: A. 16 to 20
1. The trachea is built from stacked C-shaped pieces of hyaline cartilage joined by dense connective tissue.
2. The count given is 16 to 20 pieces.
3. So the first option is correct.
4. The cartilages hold the tube open, which is why so many stacked rings are needed along its length.
