Answer: (C)

Verified step by step guidance

1. Understand the role of digestive enzymes: Digestive enzymes are proteins that help break down food into smaller molecules for absorption in the small intestine.
2. Identify the organ responsible for producing digestive enzymes: The pancreas is the primary organ that produces a variety of digestive enzymes, including amylase (for carbohydrates), lipase (for fats), and proteases (for proteins).
3. Clarify the function of other organs mentioned: The duodenum is the first part of the small intestine where digestion begins, but it does not produce enzymes. The liver produces bile, which aids in fat digestion but is not an enzyme. The gallbladder stores bile but does not produce enzymes.
4. Connect the pancreas to the small intestine: The pancreas releases its digestive enzymes into the small intestine through the pancreatic duct, specifically into the duodenum, to aid in digestion.
5. Conclude that the pancreas is the major source of digestive enzymes in the small intestine, as it produces and secretes the necessary enzymes for breaking down macronutrients.
