Original Khojo Papers practice question — not from a past board paper.
Answer
A diploblastic animal has only two germ layers, an outer ectoderm and an inner endoderm with a non-cellular mesogloea between them; a jellyfish is an example. A triploblastic animal has a third layer, the mesoderm, between the two, from which the muscles and most internal organs develop; an earthworm is an example.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Only triploblastic animals can develop a true coelom.
