A
motilin
B
gastrin
C
cholecystokinin
D
Gastric inhibitory polypeptide
Explanation: 

Detailed explanation-1: -Gastrin is a hormone that is produced by ā€˜Gā€™ cells in the lining of the stomach and upper small intestine, and released into the blood circulation. During a meal, gastrin stimulates the stomach to release gastric acid (hydrochloric acid).

Detailed explanation-2: -gastrin, any of a group of digestive hormones secreted by the wall of the pyloric end of the stomach (the area where the stomach joins the small intestine) of mammals. In humans, gastrin occurs in three forms: as a 14-, 17-, and 34-amino-acid polypeptide.

Detailed explanation-3: -Gastrin is produced by cells, called G cells, in the stomach lining. When food enters the stomach, G cells trigger the release of gastrin in the blood. As blood levels of gastrin rise, the stomach releases acid (gastric acid) that helps break down and digest food.
