Correct option is D)
Gastrin is a peptide hormone that stimulates the secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility.
It is released by G cells in the pyloric antrum of the stomach, duodenum, and pancreas. It also stimulates the mucosal growth in an acid-secreting part of the stomach. Hence, option D is correct.
