Answer 1

The correct option is D Increase absorptive surface for digested food

A typhlosole is an internal fold of the intestine or the intestinal wall. In earthworms, typhlosole is a dorsal flap of the intestine that runs along most of its length, effectively forming a tube within a tube, and increasing the absorption area by that of its inner surface. Its function is to increase the intestine surface area for more efficient absorption of digested nutrients. So, the correct answer is option D.
