Which of the following is common for the passage of food and air?

The pharynx can be divided into three portions. The nasopharynx is located behind the nasal cavity. The oropharynx is situated behind the oral cavity. The laryngopharynx is the lowermost section extending from the hyoid bone to the entrance of the oesophagus. The nasopharynx serves as a passageway for air but not food. The oropharynx and laryngopharynx function as a common pathway for both air and food.
