• A. 24 to last
• B. 25-35 segments only
• C. 26 to last

Answer 1

The correct option is C 26 to last

Typhlosole is an internal fold of the dorsal wall in earthworm. Typhlosole is present between the ${26}^{th}$ to last segment. Except the l23rd-25th segments from the last. The folded portion increases the surface area for the absorption of food in the intestine of earthworm.
