Correct answer: C. Gastric secretion increase
- A. Bicarbonate secretion
- B. Augments the action of CCK
- C. Gastric secretion increase
- D. Contraction of pyloric sphincter
Explanation
Secretin stimulates bicarbonate-rich pancreatic secretion and potentiates CCK, while it inhibits gastric acid secretion. Its inhibitory effect on gastric secretion is therefore the response it does not cause.
