Correct Answer is A
Explanation
a. Epiglottis: The epiglottis is a small flap of cartilage located above the larynx (voice box). During swallowing, the epiglottis folds down to cover the opening of the trachea, preventing food or drink from entering the airway and causing choking.
b. Vestibular fold: Vestibular folds are also known as false vocal cords. They do not play a major role in preventing food or drink from entering the airway.
c. Uvula: The uvula is a small, fleshy projection hanging from the back of the soft palate. It does not directly cover the trachea during swallowing.
d. Cricoid cartilage: The cricoid cartilage is a ring-shaped cartilage located at the base of the larynx. It provides structural support and does not move significantly during swallowing.
