Correct Answer: Option B

Explanation

The alveoli are the tiny air sacs in the lungs where gas exchange occurs between the air in the lungs and the blood. The alveolar epithelium is the thin layer of cells that makes up the walls of the alveoli. This epithelium is composed of nonciliated squamous cells, which are very thin and flat, allowing for efficient gas exchange. These cells are also very delicate and are susceptible to damage from various factors such as pollution and smoking. Damage to the alveolar epithelium can lead to various lung diseases, such as emphysema.
