Answer:4) 14th
Explanation:
Pheretima is a genus of earthworms discovered ordinarily in New Guinea and elements of Southeast Asia. Species belonging to the genus Pheretima have a clitellum, that is a band of glandular tissue gift on segments 14 to 16.Except for the first, clitellar and closing segment, all of the different segments have 8 setae placed round every segment.
The setae seem like small bristles protruding of the earthworm’s skin. The setae may be retracted and are for shifting thru the soil. The bristle-like setae anchor the segments as they crawl.
