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.
