Correct option is D)

Trypsinogen is the inactive form of digestive enzyme trypsin. It is found in pancreatic juice, along with the other digestive enzymes like amylase, lipase, and chymotrypsinogen. It is activated by enteropeptidase in the duodenum to form trypsin which acts on the proteins.
Chymotrypsinogen is the inactive precursor of digestive enzyme chymotrypsin which is released in the duodenum. It is activated by trypsin and is involved in protein digestion. Thus, the correct answer is option D.
