Question

Choose the correct answers from the alternatives given.
More complex animals have a .......... between the gut and body wall;

• A. pharynx
• B. coelom
• C. pseudocoelom
• D. arthenteron

Answer 1

The correct option is B coelom

The coelom is a fluid-filled cavity, it protects the organs from shock and compression. Simple animals, such as worms and jellyfish, do not have a coelom. All vertebrates have a coelom that helped them evolve complex organ systems. Animals that do not have a coelom are called acoelomates.

So, the correct option is, 'coelom'.
