Answer:
In anatomical directional terminology, the esophagus is <u>posterior</u> to the mouth (option d).
Explanation:
The esophagus is a tubular organ that is part of the digestive system and its function is to carry food from the mouth to the stomach.

This anatomical relationship allows the direction of food movement to be mouth → esophagus → stomach.
