c. Larynx: The larynx, also known as the voice box, is located in the throat and contains the vocal cords. These are two folds of muscle that vibrate when air passes over them, producing sound for speech.

d. Epiglottis: The epiglottis is a small flap of cartilage that covers the opening of the larynx during swallowing. It does not contain vocal cords.
