Trypsinogen is activated and converted into trypsin with the help of enzyme
procarboxypeptidase
enterokinase
chymotrypsinogen
Carboxypeptidase
Trypsinogen is activated by an enzyme, enterokinase, secreted by the intestinal mucosa into active trypsin, which in turn activates the other enzymes in the pancreatic juice. Hence, the correct answer is option b.
