Verified step by step guidance

Understand the function of the trachea: The trachea is part of the respiratory system and serves as a passageway for air. Its lining must be specialized to trap debris and move mucus to keep the airway clear.

Review the characteristics of epithelial tissue types: Transitional epithelium is found in areas like the bladder, Simple squamous epithelium is specialized for diffusion and is found in areas like alveoli, and Stratified squamous epithelium is protective and found in areas subject to abrasion like the skin or esophagus.

Learn about Pseudostratified ciliated columnar epithelium: This tissue appears layered (pseudo-stratified) but is actually a single layer of cells with nuclei at different heights. It contains cilia and goblet cells that produce mucus, making it ideal for trapping and moving particles in the respiratory tract.

Connect the function of the trachea to the tissue type: The trachea requires a lining that can trap debris and move mucus effectively, which is the role of pseudostratified ciliated columnar epithelium.

Conclude that pseudostratified ciliated columnar epithelium is the correct answer because it matches the functional requirements of the trachea's mucosa lining.
