B.
mouth  → esophagus  → stomach  → small intestine  → large intestine  → anus

C.
mouth  → stomach  → small intestine  → pancreas  → liver  → large intestine  → anus

D.
mouth  → stomach  → pancreas  → small intestine  → liver  → large intestine  → anus

Answer 1

B

Correct sequence: mouth → esophagus → stomach → small intestine → large intestine → anus. (Pancreas and liver are accessory organs that secrete into the tract, but food does not pass through them.)
