Solution

The correct option is B They all have flattened bodies.
Tapeworm, liver fluke, and Planaria belong to the phylum Platyhelminthes. All of them have flattened bodies.
Platyhelminths do not have a coelom. Planarians are the only free-living platyhelminths, the other two are parasitic.
So, the correct answer is option B.
