Which substance stimulates the secretion of pancreatic juice that is high in water and electrolytes but low in enzyme content?

Explanation

Cholecystokinin primarily triggers the release of pancreatic juice that contains a high concentration of digestive enzymes. However, secretin stimulates the secretion of pancreatic fluid that is rich in water and bicarbonate ions but low in enzymatic content. Since the question focuses on fluid rich in water and electrolytes but poor in enzymes, secretin is the hormone responsible. Pancreatozymine and proteins do not directly cause this specific secretion.
