cholecystokinin

secretin
C
glucagon
D
enterokinase
Explanation: 

Detailed explanation-1: -Enteropeptidase (enterokinase) is an enzyme secreted from intestinal glands (the crypts of Lieberkuhn) following the entry of ingested food passing from the stomach. It converts trypsinogen (a zymogen) into its active form trypsin, resulting in the subsequent activation of pancreatic digestive enzymes.

Detailed explanation-2: -Enterokinase is a protease of the intestinal brush border that specifically cleaves the acidic propeptide from trypsinogen to yield active trypsin. This cleavage initiates a cascade of proteolytic reactions leading to the activation of many pancreatic zymogens.
