If villi are absent in the small intestine, why may the body get less energy even after digestion is complete?
Answer and explanation
Correct answer: Because absorption of digested food will be reduced
The governing concept is absorption in the small intestine. Digestion only breaks complex food into soluble substances; the body receives usable nutrients after those substances pass through the intestinal wall into blood or lymph. Villi provide a large surface area and a short route for absorption. Without them, absorption falls and less nutrient material reaches cells for respiration and energy release. Thus A is correct; the other options concern unrelated organs or false processes.
