Explanation:

Digestive enzymes help break down food into smaller molecules for absorption. Let's analyze each option:

Pepsin → (A)

• A digestive enzyme found in the stomach that breaks down proteins into smaller peptides.

Renin (Rennin) → (B)

• Found in infants, it helps in the digestion of milk proteins by curdling milk.

Amylopsin (Pancreatic Amylase) → (D)

• A digestive enzyme secreted by the pancreas that breaks down starch into maltose.

Insulin → (C)

• Not a digestive enzyme. It is a hormone produced by the pancreas that regulates blood sugar levels.

Since insulin is a hormone, not a digestive enzyme, the correct answer is (C) Insulin.
