D. Hyaline cartilage
Explanation:
Hyaline cartilage forms incomplete C shaped rings which surround the trachea. It is translucent cartilage. The rings lie posterior to the trachea. It supports the wall of the trachea and prevents its collapse during inspiration. The circoid, thyroid, and arytenoid rings are made of up hyaline cartilage. Elastic cartilage forms the epiglottis. It has great flexibility and allows repeated bending. Fibrocartilage is tough, very strong tissue found predominantly in the intervertebral disks.
