• A. Asthma
• B. COPD
• C. Emphysema
• D. Bronchitis

Answer: (D)

Inflammation of the bronchial tubes is called bronchitis. The bronchi are the air passages that carry air from the trachea into the lungs, and when they become inflamed they swell and often produce extra mucus, leading to coughing and sometimes chest tightness or wheezing. This term is specific to the inflammation of those airways, unlike other conditions: asthma involves reversible airway narrowing and hyperreactivity, emphysema centers on damage to the air sacs (alveoli), and COPD is a broader disease category that can include chronic bronchitis and emphysema. Understanding that bronchitis names the inflammation of the bronchi helps distinguish it from these related but different lung issues.
