Answer
The question asks which group has body segments divided into 31 or 17.
- Echinodermata (Option A) are unsegmented animals, so this option is incorrect.
- Polychaeta (Option B) and Oligochaeta (Option C) are classes of annelids (segmented worms). While they are segmented, the number of segments is typically highly variable and often much greater than 31 or 17.
- Hirundea (Option D) is the class of leeches, which are also annelids. Leeches are characterized by having a fixed and definite number of segments, although the most commonly cited number is 33 or 34. However, compared to other annelid classes where segment numbers are highly variable, Hirundea is the only group among the options known for having a specific, fixed, and relatively small number of segments. Therefore, it is the most appropriate answer for a group with a specific segment count like 17 or 31.
