Question

Assertion (A): Tobacco users face a high risk of lung cancer.

Reason (R): The polycyclic hydrocarbons in nicotine inhaled during smoking are carcinogenic.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Tobacco smokers have a high risk of lung cancer. Carcinogenic polycyclic hydrocarbons in tobacco smoke help explain this risk; the wording in the reason is imprecise because these hydrocarbons are in the smoke, not in nicotine.
