Correct option is C)
Gastrin is a peptide hormone that stimulates the secretion of gastric acid (HCl) by the parietal cells of the stomach and helps in gastric motility or digestion.
It is released by G cells in the pyloric antrum of the stomach, duodenum, and pancreas.
Hence, Gastrin is a hormone that is released from the gastrointestinal tract and helps in digestion.
The presence of gastrin stimulates parietal cells of the stomach to secrete hydrochloric acid (HCl) or gastric acid.
Trypsin is produced as the inactive trypsinogen in the pancreas. When the pancreas is stimulated by cholecystokinin, it is then secreted into the first part of the small intestine.
Hence, it promotes the secretion of HCl but not of trypsinogen.
So, the correct answer is 'Assertion is correct but Reason is incorrect'.
