Correct Option (b) Duodenum

Explanation:

Secretin is a polypeptide hormone secreted by the mucosa of duodenum and jejunum.

It perform two functions : (a) It stimulates sodium bicarbonate from the pancreas which neutralises the acid in the chyme so that it will not damage the wall of the small intestine. (b) It increases the rate of bile secretion in the liver.
