Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Tobacco smoke irritates and damages the airways over many years.
Step 2: Chronic bronchitis
The bronchi become inflamed with excess mucus and a persistent cough.
Step 3: Emphysema
The alveolar walls break down, which reduces the surface for gas exchange. Together these form COPD.
Step 4: Other conditions
Sinusitis, laryngitis and pneumonia are mainly infections. They are not the diseases attributed to smoking here.
Final Answer:
Smoking causes chronic bronchitis and emphysema, that is C and D only. \[ \boxed{\text{(B) }\text{C and D only}} \]
