Answer: D

Explanation:

Definition of Emphysema:

Emphysema is a chronic lung condition characterized by the destruction of the alveoli (air sacs) walls.

This leads to reduced surface area for gas exchange and difficulty in breathing.

It is a major component of Chronic Obstructive Pulmonary Disease (COPD).

Differentiation from Other Conditions:

Asthma: A condition where the airways become inflamed and narrowed.

Bronchitis: Inflammation of the bronchial tubes, often resulting in cough and mucus production.

Bronchiolitis: Inflammation of the small airways (bronchioles), commonly seen in children.
