• A. stomach
• B. oesophagus
• C. trachea
• D. small intestine

Answer 1

The correct option is D small intestine

• Food that you consume in your diet contains carbohydrates, proteins and fats. Some digestion occurs in the stomach but mostly takes place in the small intestine.
• The purpose of the small intestine is to finish digestion and absorb nutrients.
• The small intestine is where most chemical digestion takes place.
• Many of the digestive enzymes that act in the small intestine are secreted by the pancreas and liver and enter the small intestine via the pancreatic duct. Hence, most of the digestion in human GIT takes place in the small intestine.

So, the correct answer is 'small intestine'.
