Question 7
A

Starch

B

Starch, protein and fats

C

Oils and fats

D

Proteins

Explanation

The correct answer is B. Starch, protein, and fats.

The pancreas plays a crucial role in the digestion of food. It produces enzymes that break down carbohydrates, proteins, and fats in the small intestine. If a man's pancreas is removed by surgical operation, it can affect the digestion of all three macronutrients: starch, protein, and fats. 

Without the enzymes produced by the pancreas, starches cannot be broken down into simpler sugars, proteins cannot be broken down into amino acids, and fats cannot be broken down into fatty acids and glycerol. As a result, the body may not be able to absorb these nutrients properly, leading to malnutrition and other health problems.
