Answer:
The best answer to the question: The vocal folds are located within the:___, would be, B: Larynx.
Explanation:
The larynx is the structure that is responsible for conducting air from the upper airway passages towards the lungs, and protecting the trachea and lower airway passages from being contaminated by food and fluids. In order to do this, this tube counts with motility and a series of cartilaginous structures that support it and aid it in its function. At the very end of the larynx, and at the opening of the trachea, we can find the vocal folds, which is where the vocal cords are located. These folds have a double function: they produce sound when air moves in a certain way from lungs to upper air passageways, through vibration. And most important of all, they produce the coughing reflex if any particle, especially food, touches them. They will close if constant contact with the particle persists, and will continue producing the reflex until the particle has been dislodged and expelled.
