I have been asked this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Animals Structural Organisations in chapter Structural Organisations in Animals of Biology – Class 11

Answer 1

The correct answer is (c) Increases the surface area for absorption

For explanation I would say: Typhlosole is present in the intestine after the 26^th segment. It arises from the median fold of the dorsal wall. It increases the surface area of absorption of nutrients from the digested food material.
