Consider the following statements about small intestine and select the one which is NOT correct:

The correct option is (d) because the statement is incorrect. The absorption of water from unabsorbed food is the function of the walls of the large intestine, not the villi of the small intestine. The villi in the small intestine are specialized for absorbing digested nutrients (like glucose, amino acids, fatty acids, and glycerol).

• Option (a) is a correct statement: Herbivores have a longer small intestine to digest cellulose, while carnivores have a shorter one because meat is easier to digest.
• Option (b) is a correct statement: The small intestine is indeed the site of complete digestion of carbohydrates, proteins, and fats.
• Option (c) is a correct statement: The small intestine receives bile juice from the liver and pancreatic juice from the pancreas to facilitate digestion.
