Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. small intestine.

  • The small intestine is the site of complete digestion of carbohydrates, proteins and fats in the human body.
  • In the small intestine, macronutrients are broken down into their basic units by specific digestive enzymes:
    • Carbohydrates are broken down into glucose and fructose by the enzyme amylase.
    • Proteins are broken down into amino acids by proteases.
    • Fats are broken down into fatty acids and glycerol by the enzyme lipase.
  • Additionally, the small intestine is responsible for the absorption of water and electrolytes, which is crucial for maintaining the body’s fluid and electrolyte balance.
