Explanation

The pharynx (throat) is a muscular tube that begins at the back of the nose and continues to the neck. It contains three sections: the nasopharynx (nasal), which is the part where the nasal passage joins the pharynx and through which the air enters the trachea and lungs; the oropharynx (oral), which is a cartilaginous structure that closes the passage between the pharynx and the larynx as swallowing takes place; and the laryngopharynx (laryngeal), which is the part that connects to the esophagus in the digestive tract and the larynx of the respiratory system. So, the correct answer is A. The nasal, oral, and laryngeal.
