• B. Secretin
• C. Cholecystokinin
• D. Both b and c

Answer 1

The correct option is C Cholecystokinin

Cholecystokinin is a hormone secreted by cholecystokinin cells in the mucosa of the small intestine. It stimulates the secretion of pancreatic juice which is rich in enzymes. It also stimulates the contraction of the gallbladder and releases bile juice.

Secretin is a hormone that is secreted by the enteroendocrine cells of the mucosal layer of the duodenum. It stimulates the secretion of pancreatic juice that is rich in bicarbonate ions.

Gastrin is a hormone that is secreted by the G cells of the gastric glands. It promotes secretion of gastric juice and increases gastric motility.
