Answer/s:4. C. It guards the entrance of the trachea and closes when food is swallowed to prevent food from entering.The epiglottis is a small flap of tissue located at the entrance of the trachea (windpipe). Its main function is to prevent food or liquid from entering the airway when swallowing. It automatically closes over the trachea when we eat and opens when we breathe, ensuring that air goes into the lungs while food goes into the esophagus.IF YOU FOUND THIS HELPFUL, PLEASE MARK IT AS BRAINLIEST.
