The correct option is A Duodenum
The pancreas contains exocrine glands, that produce enzymes important to digestion. When food enters the stomach, these pancreatic juices are released into a system of ducts, that end in the main pancreatic duct. The pancreatic duct joins the common bile duct to form the ampulla of Vater, which is located at the first portion of the small intestine, called the duodenum.
