Answer:
B. Glottis.
Step-by-step explanation:
The correct answer is B. Glottis.
The glottis is the space between the vocal cords in the larynx. It is responsible for producing sound when air passes through it and causes the vocal cords to vibrate. The epiglottis is a flap of tissue that covers the glottis during swallowing to prevent food and liquid from entering the airway. The vocal folds (also known as vocal cords) are the two bands of muscle tissue within the larynx that vibrate to produce sound. The cricoid cartilage is a ring-shaped cartilage located below the thyroid cartilage in the larynx.
