Coelom is divided into septa in case of:__________?
Correct answer: B. Annelids
- A. Molluscs
- B. Annelids
- C. Sponges
- D. Cniderians
Explanation
Annelids have a true coelom divided by transverse septa into repeated compartments, matching their segmented body plan. Molluscs have an unsegmented coelom that is greatly reduced, while sponges and cnidarians do not possess a true coelom, so students may choose molluscs because they also have a coelom.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
