Solution
The correct option is C Duodenum The duodenum is the first and shortest segment of the small intestine. It receives partially digested food (known as chyme) from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine. Cholecystokinin (CCK) is a digestive hormone released along with secretin when food from the stomach reaches the first part of the small intestine (duodenum).
