Solution
The correct option is A Earthworm
The coelomic fluid present in annelids helps
them in locomotion and fluid regulation through their body walls. The pH of
their coelomic fluid plays a very important role in the process of osmoregulation
and in the selection of their habitat.
So, the correct answer is 'Earthworm'.
