Answer 1

Correct answer: A). Smoking damages cilia in the trachea and more particles enter the lungs

Tar is a particulate matter that is generated by the burning of tobacco, in a form of cigarette smoke. It contains a variety of inorganic and organic chemicals like carbon dioxide, nitrogen, oxygen, carbon monoxide, and volatile compounds.

Smoking is known to destroy the cilia, fine hair that is known to be found in the upper airways that help to protect against the infection. If cilia are damaged then tar can more easily penetrate into the lungs can cause more damage and may cause cancer.
