Ans: B
Feedback:
During swallowing, the free edges of the epiglottis move downward to cover the larynx, thereby preventing liquids and foods from entering. When substances other than air manage to enter the airway, the vocal folds serve as a sphincter, causing the larynx muscles to constrict and close and/or collapse the airway as a protective measure.
