The correct statement will be - B
The epiglottis closes off the glottis.
Explanation:
During the swallowing reflex - the epiglottis closes off the glottis.
Our respiratory and digestive system shares a common path. At the time of swallowing something, the epiglottis closes off the glottis which helps the food to go downwards further easily. Otherwise, there is a chance that the food can enter the windpipe and can choke a person. Sometimes this could be fatal.
