A list of animals (i-viii) is given. Classify them as acoelomates, coelomates and pseudocoelomates and select the correct option.$\left(i\right)Adamsia\left(ii\right)Wuchereria$(iii) Nereis (iv) Earthworm$\left(v\right)Planaria\left(vi\right)Ascaris$(vii) Liver fluke (viii) Scorpion  

Acoelomates are those animals which do not have coelom (body cavity), e.g., coelenterates {Adamsia} and flatworms (Planaria and liver fluke). Coelcinates are the organisms with true coelom, e.g., annelids (Nereis and earthworm) and arthropods (scorpion). Pseudocoelomates have false coelom, e.g., nematodes (Wuchereria and Ascaris).
