Solution
The correct option is D Trachea
C-shaped cartilaginous rings are present in trachea which prevent the trachea from collapsing. The trachea or the wind pipe is lined with cilia bearing pseudostratified columnar glandular epithelium.
The mucous secreted by the glandular cells helps in trapping germs and dust particles and the cilia keep beating to sweep away excess mucus from the trachea.
