Explanation
The pharynx is a muscular tube that extends from the base of the skull to the esophagus and is the common passage for both food and air in humans. It is located behind the nasal cavity, mouth, and larynx, and is divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. The esophagus, on the other hand, is a muscular tube that connects the pharynx to the stomach and is part of the digestive system. Therefore, option A is incorrect. Option C is incorrect because the larynx is also known as the voice box and is part of the respiratory system, but it is not a common passage for both food and air. Option D is incorrect because the nasopharynx is the upper part of the pharynx that connects the nasal cavity to the oropharynx, but it is not the common passage for both food and air.
