Answer 1

The correct option is A Their body have true coelom.

Members of phylum Platyhelminthes, have a slender and flat body, so they are known as 'flatworms'. They are acoelomates which means that there is no body cavity between body and internal organs. These are triploblastic i.e. their body is made up of three germ layers- endoderm, ectoderm and mesoderm. Also, these organisms are hermaphrodites which means that male and female reproductive systems are present in the same animal body.
