Solution

The correct option is B epiglottis
Epiglottis stands open during breathing, allowing air into the larynx. During swallowing it closes to prevent aspiration, forcing the swallowed liquids or food to go into the esophagus instead. It is thus the structure that diverts passage air into the trachea and food into the esophagus
So, the correct answer is 'epiglottis'
