Answer 1

Hint The gastrointestinal tract is the part of the digestive system and it is also known as the alimentary canal. The gastrointestinal tract’s vital function is to provide nutrients to our body through the process of ingestion, motility, secretion, digestion, and absorption.
Complete Step-by-step answer:
Digestive system constitutes the gastrointestinal tract and another organ that assist to break down food into simpler substances so that body can easily absorb them. The digestive system breaks down food into nutrients with the help of a variety of enzymes and hormones.
Gastrin is a hormone that is generated by the stomach. It stimulates gastric motility and the release of hydrochloric acid into the stomach. During meal time gastrin stimulates the stomach to release gastric acid.
Secretin is a gastrointestinal peptide hormone that regulates the secretion in the stomach, pancreas, and liver. The hormone is generated from enterochromaffin cells in the duodenum. The main function of secretin is to stimulate the pancreas to secrete pancreatic juice. In addition to this, it is also responsible for body fluid homeostasis and bile production.
Cholecystokinin(CCK) stimulates the secretion of pancreatic enzymes and bile juice by the gallbladder.
The gastric inhibitory polypeptide(GIP) is a hormone that is secreted by the cells of the intestinal mucosa. its main role is to stimulate insulin secretion and inhibits gastric production and motility.
Hence the correct answer is option C.
Note: The gastrointestinal tract is a long twisting tube that starts from the mouth and goes through the oesophagus, stomach, small intestine, large intestines, and anus.
