- B. Pancreatic juice
- C. Bile

Explanation
Pancreas has complete set of enzymes for digestion of all principal components (carbohydrates, proteins and lipids) of food. Pancreatic juice contains various digestive enzymes that are capable of digesting all the principal components of food. These enzymes include amylases (for carbohydrate digestion), lipases (for lipid digestion), and proteases (for protein digestion). The pancreas plays a crucial role in producing and secreting these enzymes into the small intestine, where they act on the different components of food.
