Cnidarians develop only two germ layers during embryonic development. They are therefore described as:
AAcoelomate
BTriploblastic
CDiploblastic
DPseudocoelomate
Answer & Solution
Correct answer: C. Diploblastic
1. Cnidarians form only endoderm and ectoderm.
2. Having two germ layers makes them diploblastic.
3. Rule out triploblastic: that requires a third layer, mesoderm.
4. Acoelomate and pseudocoelomate describe body cavity, not germ layer count.
