A 56-year-old woman is evaluated for a 2-year history of episodic cough and chest tightness. Her symptoms began after a severe respiratory tract infection. Since then, she has had cough and chest discomfort after similar infections, typically lasting several weeks before resolving. She feels well between episodes. She is otherwise healthy and takes no medications. Physical examination reveals no abnormalities. Chest radiograph and spirometry are normal.
Which of the following is the most appropriate next diagnostic test?

(A) Bronchoscopy
(B) CT scan of the sinuses
(C) Exercise echocardiography
(D) Methacholine challenge test
