Detailed explanation-1: -Enterocoelom is a true coelom that develops as lateral pouches from the embryonic gut (archenteron). This type of body cavity is formed by out pocketing of the primitive gut that breaks off and forms the coelom. This cavity is lined by cells of mesodermal origin.

Detailed explanation-2: -So, the correct answer is ‘Hemichordata’.

Detailed explanation-3: -Enterocoelom is a true coelom which develops as lateral pouches from the embryonic gut (archenteron), e.g., Echinodermata and Chordata. This cavity is lined by cells of mesodermal origin.

Detailed explanation-4: -Coelomic pouches are mesodermal structures produced by all animals with a body cavity. That future adult body cavity is called a coelom, and its lining originates in the sea urchin from the mesodermal coelomic pouches (CPs).

Detailed explanation-5: -Development of the Coelom The coelom of most protostomes is formed through a process called schizocoely, when a solid mass of the mesoderm splits apart and forms the hollow opening of the coelom.
