Final answer:
The false statement about Clara cells is that they line conducting bronchioles along with goblet cells. Clara cells instead contribute to the production of surfactant and do not produce mucus like goblet cells do. Therefore correct option is B
Step-by-step explanation:
The statement about Clara cells which is false is: 'Lines conducting bronchioles along with goblet cells.' Clara cells, also known as bronchiolar cells, are non-ciliated and do not line the bronchioles with goblet cells. Goblet cells are responsible for mucus production and are part of the pseudostratified columnar epithelium lining the respiratory tract, such as the trachea and larger bronchi. Clara cells are found in the lining of the bronchioles and have a characteristic dome-shaped apical portion that protrudes into the lumen, but they do not produce mucus like goblet cells. They are involved in the secretion of some components of surfactant, which helps to maintain the patency of the bronchioles.
