Answer : b
Hints & Solution
(b) Inhibition of gastric juice secretion is done by a hormone (secreted by the intestinal mucosa) called enterogastrone while stimulation of gastric juice secretion is done by the hormone gastrin secreted by the pyloric stomach mucosa. On the other hand pancreatic & bile secretions are controlled by a hormone complex cholecystokinin pancreozymin (CCKPZ) secreted by the intestinal mucosa.
