Solution
The correct option is C (1) Platyhelminthes, (2) False coelom, (3) Triploblastic In the animal kingdom, different Phylums have different characteristics. For example, ∙ Phylum Platyhelminthes - The animals belonging to this phylum are triploblastic. They lack body cavity and hence are called acoelomates. ∙ Phylum Nematoda - The animals belonging to this phylum are triploblastic but they have a body cavity lined by patches of mesoderm. Thus they are considered as psuedocoelomates. ∙ Phylum Annelida - The animals belonging to this phylum are triploblastic with true body cavity (eucoelomates).
