B Correct answer
Explanation

The epiglottis is a flap-like structure located at the entrance of the larynx (wind pipe). When you swallow, it closes over the larynx to prevent food or liquid from entering the respiratory tract. The glottis is the vocal cord opening, larynx is the voice box, and pharynx is the shared passage for both air and food - none of these prevent entry.
