Solution

The correct option is C Hyaline cartilage
The trachea is also called as windpipe. It is a cartilaginous tube which connects pharynx and larynx to the lungs, allowing passage of air. The wall of the trachea is lined by C shaped incomplete cartilaginous rings to protect it from collapsing during the breathing process due to pressure exerted on its walls by the air. These incomplete rings are made up of hyaline cartilage.
So, the correct answer is 'Hyaline cartilage'.
