Answer:
Correct Answer: C
Solution:
Nicotine is a highly addictive chemical compound present in tobacco. When tobacco is smoked, nicotine is absorbed through the wall lining of the small air sacs in the lungs.
Phenol is another harmful chemical found in tobacco smoke. It’s a toxic, colorless crystalline solid with a sweet tarry odor. It’s used as a disinfectant and is also found in resins, plastics, and pharmaceuticals.
Tar is a sticky brown substance produced by cigarettes that can stain a smoker’s fingers and teeth yellow-brown. It’s also sometimes called total particulate matter and is inhaled when a cigarette is smoked.
