• B. Causes weakening and paralysis of cilia in the upper respiratory tract
• C. Leads to addiction
• D. Affects only in combination with nicotine

Answer 1

The correct option is B Causes weakening and paralysis of cilia in the upper respiratory tract

Tar is a sticky brown substance present in cigarette smoke. Tar that enters the lungs along with cigarette smoke destroys or paralyzes the cilia, which are tiny hairs lining the upper airways and protecting the body from infection. When the cilia get damaged, tar penetrates the lungs and causes more damage. Immediate health effects caused by tar include shortness of breath and coughing.
