The correct answer is epiglottis.

The small flap of tissue that closes the windpipe when you swallow food to prevent choking is called the epiglottis.

Its main function is to close the windpipe, or the trachea, when you swallow food or liquids. This prevents them from entering the airway and going down the wrong pipe, which could result in choking.
