AA leaf-shaped flap of elastic cartilage
BA ring, wide behind and thin in front
CA pair of small pyramidal cartilages
DA C-shaped bar open at the back
Answer & Solution
Correct answer: B. A ring, wide behind and thin in front
1. The cricoid cartilage is the thick inferior cartilage of the larynx.
2. It forms a complete ring with a wide posterior region and a thinner anterior region.
3. So the second option is correct.
4. A C-shaped bar open at the back describes the tracheal cartilages, not the cricoid, which is the trap in the fourth option.
