B
larynx
C
trachea
D
epiglottis
Explanation: 

Detailed explanation-1: -A small flap of tissue called the epiglottis (eh-pih-GLAH-tus) protects the larynx. When we swallow, the epiglottis covers the larynx to prevent food and liquid from going into the lungs. The trachea (windpipe) is the part of the airway that continues below the larynx (LAIR-inks).

Detailed explanation-2: -Overview. The epiglottis is flap of cartilage located in the throat behind the tongue and in front of the larynx. The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs.

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.

Detailed explanation-4: -Composed mostly of elastic cartilage, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.
