Explanation of Solution

Coelom is the main body cavity in various animals. It is found between the body wall and the intestinal canal.

The animal that does not have any body cavity is known as acoelomate. These animals lack fluid-filled cavity between the intestinal canal and the body wall.

The pseudocoelom is the fluid-filled cavity found in the nematode. It lies inside the external body wall and bathes the internal organs.
