Which of these is a function of the large intestine?

  • A. nutrient absorption
  • B. bile production
  • C. water absorption
  • D. enzyme secretion
Correct Answer: C

Rationale: The correct answer is C: water absorption. The large intestine's main function is to absorb water and electrolytes from the indigestible food residue that enters it from the small intestine. This process helps in the formation of solid feces. Nutrient absorption primarily occurs in the small intestine (A). Bile production is done by the liver and stored in the gallbladder, not in the large intestine (B). Enzyme secretion primarily occurs in the small intestine and other digestive organs, not in the large intestine (D). Therefore, C is the correct answer as it aligns with the main function of the large intestine.
