E. Both A and B are correct.

Answer 1

e is the answer  simply turbellaria isn't parasitic, and cestoidea and trematoda are parastic...hopefully this helps good luck

Answer 2

E. Both A and B are correct.

Turbellarians are not parasitic. Only the two groups (tapeworms and flukes) are parasitic. in fact if you cut a liver of a cow you will find quite a number of liver flukes. tapeworms are often present in mammals including dogs,cats and even man.

Hope this helps...
