A 15-year-old boy is sent for diagnostic testing following symptoms of wheezing and coughing during outdoor football practice. The findings showed reversible airway obstruction secondary to bronchial hyperreactivity, airway inflammation, mucus plugging, and smooth muscle hypertrophy. Which of the following is most consistent with these findings?

Choice A reason: Pneumonia presents with infection-related symptoms and radiographic changes, not reversible airway obstruction or hyperreactivity. Choice B reason: Correct. Asthma is characterized by reversible airway obstruction, bronchial hyperreactivity, inflammation, and structural changes like smooth muscle hypertrophy, which matches this clinical picture. Choice C reason: Bronchitis involves inflammation of the bronchi, often due to infection, and does not typically produce reversible airway obstruction or chronic airway changes. Choice D reason: Sinusitis affects the sinuses, not the lower airways, and would not account for wheezing or bronchial hyperreactivity.
