Question

In Pheretima, the segments without setae are

• A. First, last and clitellar segments
• B. Only clitellar segments
• C. Only fourth segment
• D. Only second segment

Answer 1

The correct option is A First, last and clitellar segments

• Except for the first, clitellar and last segment, all the other segments have eight setae located around each segment.
• The setae look like small bristles sticking out of the earthworm’s skin. The setae can be retracted and are for moving through the soil. The bristle-like setae anchor the segments as they crawl.
  

So, the correct option is 'First, last and clitellar segments'.
