Answer : a
Hints & Solution
(a) Rennin is a milk digesting proteolytic enzyme releted to pepsin that is synthesised by chief cells in the stomach of some animals. Enterokinase, produced by cells of duodenum, is involved in digestion. It converts trypsinogen (a zymogen) into its active form trypsin, resulting in the subsequent activation of pancreatic digestive enzymes. Fructose shows facilitated transport . Oxyntic cells secrete $HCl$ and intrinsic factors that are essential for absorption of vitamin $B _{12}$
