A
Mouth
B
Stomach
C
Bronchioles
D
Epiglottis
Explanation: 

Detailed explanation-1: -A small muscular flap called the epiglottis closes to prevent food and liquid from going down the “wrong pipe”-your windpipe (trachea).

Detailed explanation-2: -First, the tongue pushes the food into the throat. Next, the epiglottis, a small but important flap of tissue, folds over the voice box at the top of the windpipe. This keeps food from going down the wrong way.

Detailed explanation-3: -A cartilaginous flap called the epiglottis is present just above the larynx. The larynx which is situated at the entrance of the windpipe is pulled upward to bring it close to the tongue when the epiglottis closes the opening of the windpipe. The epiglottis prevents food from entering it during swallowing.

Detailed explanation-4: -What is the pharynx? The pharynx, commonly called the throat, is a muscular, funnel-shaped passageway inside the body. It connects the mouth and nose to the esophagus (leading to the stomach) and larynx (leading to the trachea and then lungs).
