Answer» Correct Answer - A The coughing would have been due to improper movement of epiglotitis. Laryngopharynx possesses an aperture called glottis that leads into trachea. During the swallowing of food. Glottis is clossed by a leaf like cartilage called epiglottis, so that the food does not enter the trachea. If during eating epiglottis remains open, then the food particles may enter the trachea leading to reflex action of coughing this removes the food particles from the trachea so that the breathing does not get obstructed.
