Final Answer :
B
Explanation :
Pseudostratified columnar epithelial tissue lines the respiratory tract and provides protection against respiratory infections due to the presence of mucus-secreting goblet cells and cilia. The mucus traps foreign particles and the cilia sweep the mucus towards the pharynx or throat, where it can be expelled through coughing or swallowing.
