• A. $48$
• B. $50$
• C. $52$
• D. $49$

Answer 1

The correct option is A $48$

The typhlosole of the earthworm starts from the 27${}^{th}$ segment and continues till the segment where rectum begins. So, it continues till the last from the 23${}^{rd}$ segment. An earthworm having 100 segments will have 48 segments that will be occupied by the typhlosole.

So, the correct answer is '48'
