• A. A slowly progressive decline in mental abilities
• B. A mood disorder in which the person alternates between the hopelessness and lethargy of depression and the overexcited state of mania
• C. A clouding of the lens
• D. A chronic allergic disorder characterized by episodes of severe breathing difficulty, coughing, and wheezing

Answer: (D)

Asthma is a chronic allergic disorder characterized by episodes of severe breathing difficulty, coughing, and wheezing. These episodes happen because the airways become inflamed and temporarily narrowed, making it hard to move air in and out of the lungs. Triggers such as allergens, exercise, infections, or irritants can set off these episodes. This description fits asthma’s impact on the respiratory system, unlike the other options that point to unrelated conditions: mental decline, mood disorders, or clouding of the eye’s lens. Understanding asthma’s inflammatory, airway-narrowing nature helps explain why symptoms come and go and why treatments focus on reducing inflammation and easing airflow during episodes.
