The correct option is C: absorb fat to be transported back to the blood stream.
The villi absorb fats and fat-soluble vitamins that are essentially required by the body.
<u>EXPLANATION:</u>
Villi are small "finger-like projections" which are present on the "inner lining" of small intestine. The villi increase the surface area of the small intestine so that more nutrients can be absorbed from the food that is digested.
The centre of villi contains lymph capillaries and blood capillaries called lacteals. It is these lacteals that abort fats whereas the blood capillaries absorb water-soluble vitamins.
