Which of the following is a forced expiration technique used in airway clearance?

Forcing air out of the lungs to move secretions up the airways is the key idea here. A method that combines breathing control, thoracic expansion, and a deliberate rapid exhalation used to mobilize secretions fits that idea: it uses a clear forced expiratory component (the huff) as part of the overall technique to clear mucus. That approach is what makes it the best answer, because the huff cough is a true forced expiration maneuver designed to raise expiratory flow and shear secretions toward the mouth for clearance. Other options may loosen or mobilize mucus in different ways (such as percussion to loosen secretions or just providing humidified air or saline to help expectoration), but they don’t center on a forced expiration technique. Autogenic drainage involves controlled breathing at varying lung volumes and isn’t driven by a strong forced exhale, so it’s not the forced expiratory component in isolation.
