Correct option is C)

Solution: 
  • Option A is incorrect as oxyntic cells are secreted by the epithelial cells of the stomach.  
  • Option B is incorrect as Ptyalin converts starch into maltose.
  • Option D is incorrect as Sphincter of Oddi is present at the junction of hepato-pancreatic duct and duodenum. 
  • Option E is incorrect as oxyntic cells secrete hydrochloric acid in the stomach.
  • Hence, the correct answer is Option [C]. The Crypts of Lieberkuhn are seen at the base of villi in the intestine. These are covered by epithelium cells. These contain enterocytes, goblet cells, enteroendocrine cells, paneth cells and stem cells. The Crypts of Lieberkuhn secrete intestinal juice called succus entericus.
