Accepted Answer

The glottis is the opening between the vocal cords in the larynx, which is the passageway for air to enter and exit the lungs during breathing. Option A refers to the epiglottis, which is a flap of cartilage that covers the opening to the larynx during swallowing to prevent food from entering the airway. Option B refers to the posterior nasal aperture, which is another term for the choanae or the opening at the back of the nasal cavity that leads to the nasopharynx.
