Esophagus

The correct option is D.

Explanation of the correct option:

2. Since no digestion occurs, the food pipe does not secrete any digestive juices.
3. The food is pushed downwards towards the stomach by the regular contractions and relaxations of the food pipe wall.

Cells on the walls of the duodenum secrete intestinal juice which contains mucus and digestive enzymes to facilitate digestion.

Option B:

Bile juice is produced by the liver and stored in the gall bladder.
