Which option is NOT a mechanism by which bronchodilators improve COPD symptoms?

Explanation:
Bronchodilators help COPD symptoms by relaxing airway smooth muscle, which widens the airways, lowers airway resistance, and improves airflow. This increase in caliber translates to a higher FEV1 and better ventilation, meaning gas exchange improves and dyspnea can lessen. They do not narrow the airways; in fact, narrowing would worsen airflow. So the statement that bronchodilators narrow the airways is not a mechanism by which they improve symptoms.
