Answer
C. tunica muscularis
Explanation
The tracheal wall is composed of several layers, including the tunica mucosa, tunica submucosa, and a layer of cartilage and connective tissue. However, it does not contain a tunica muscularis, which is typically found in other parts of the respiratory system like the bronchi.
