Correct Answer: (b) (iii) They have small pores through which food can easily pass.

Explanation:

 Villi are small finger-like projections located in the walls of the small intestine.

 The structure of the small intestine is designed for the absorption of nutrients. The inside of the small intestine is lined with villi that absorb nutrients from the liquid mixture called chyme produced in the stomach from the food we eat. Their function is to increase the surface area in order to maximize the absorption of digested food.
