Answer 1

The correct option is D They only participate in digestion of fats

Intestinal villi are the numerous small finger shaped projections which increases the absorptive surface area. They contain abundant blood capillaries and lymph vessels called lacteals. They also possess countless minute microvilli which further adds to the absorptive surface.
