Answer:C) Increase the surface area to increase the efficiency of nutrient absorption
Explanation:the small intestine is the absorbing region of the alimentary canal.food ingested is digested in the stomach through the mechanical mixing of food with enzymes and also the churning of food breaks it down.
The digested food is then passed into the small intestine.in the small intestine,enzymes from the pancreas and liver acts on food.
The intestine needs a large absorption areas in order to utilize the digested food.it contains small finger-like extensions called villi and microvilli.these structure brushes against food in the intestine and increases absorption.
The wall of the intestine is also folded to increase the surface area in contact with food.
