B Correct answer
Explanation

A nephric tubule leads from each nephrostome through the septum and into the following segment. This tubule then leads to the main body fluid filtering organ, the nephridium or metanephridium, which removes metabolic waste from the coelomic fluid and expels it through pores called nephridiopores. These are found maximum in the clitellar region as this region is formed by merging two or three segments.
