Correct answer: E — Start inhaled corticosteroid-containing therapy and provide an asthma action plan

Reversible airflow obstruction with nocturnal and exercise-triggered symptoms supports asthma, and current practice favours inhaled corticosteroid-containing treatment plus a written action plan. SABA-only treatment increases exacerbation risk and is no longer preferred as sole long-term therapy. Oral prednisone is reserved for significant exacerbations rather than routine initiation. CT and antibiotics are not indicated in this typical presentation.
