What is the function of fold and villi

Option A.

Explanation:

Villi are the finger like projection present in the surface of small intestine in circular folds.

Villi is the organelle that functions to increase the surface area ( internal surface) of small intestine walls and provide more surface area for absorption. The increased surface area increases absorption of useful nutrients such as amino acid and monosaccherides and that passes into the semipermeable villi with the process of diffusion. Villi decreases the average distance travelled by nutrient molecules due to increased surface area and hence diffusion increases.

Hence, the correct option is A.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
