a
b
c
d
e

Explanation:

To solve this, we recall the structure of the trachea. Ciliated cells are part of the pseudostratified ciliated columnar epithelium lining the trachea's lumen. In the diagram, the layer with ciliated cells (for moving mucus with particles) is indicated by letter C. This is because ciliated cells in the tracheal lining (respiratory epithelium) perform the mucociliary clearance, moving debris - laden mucus toward the pharynx.
