Answer 1

The correct option is C 26${}^{th}$

A typhlosole is an internal fold of the intestine or the intestinal wall it runs along most of its length, effectively forming a tube within a tube and increasing the absorption area by that of its inner surface. In earthworm, it begins from the 26th segment. So, the correct answer is option C.
