Answer and Explanation

The Correct Answer is B

B. Mouth, pharynx, esophagus, stomach, small intestine

This accurately follows the correct path of food through the digestive system.

C. Mouth, esophagus, stomach, pharynx, small intestine

The pharynx comes immediately after the mouth, not after the stomach.

D. Mouth, pharynx, stomach, esophagus, anus

The esophagus comes before the stomach, and this sequence is incorrect and incomplete.
