Select the incorrect match with respect to the basis of classification in animals:

Options

  1. AHemichordata - Organ-system level of organisation
  2. BAschelminthes - Coelomate condition
  3. CEchinodermata - Triploblastic organisation
  4. DCtenophora - Tissue level of organisation

Correct answer

B. Aschelminthes - Coelomate condition

Step-by-step solution

Aschelminthes are pseudocoelomates, meaning their body cavity is not lined by mesoderm. Instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Hemichordates have an organ-system level of organisation. Echinoderms are triploblastic and coelomate animals. Ctenophores possess a tissue level of organisation. Answer: Aschelminthes - Coelomate condition
