B

C

D

Explanation: 

Detailed explanation-1: -The flap that covers the trachea during swallowing so that food does not enter the lungs. Anatomy of the larynx. The three parts of the larynx are the supraglottis (including the epiglottis), the glottis (including the vocal cords), and the subglottis.

Detailed explanation-2: -The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe. Swelling of the epiglottis can completely block the airway. This can lead to breathing or respiratory failure. In this life-threatening condition, the level of oxygen in the blood drops very low.

Detailed explanation-3: -The glottis is the narrowest part of the larynx and opens into the airway. Vocal cords make lateral borders of it. Epiglottis, a leaf-shaped cartilaginous flap, prevents the food to enter the airway passage of the respiratory system while swallowing.
