"The correct option is (c) sponges.

Excretory system has two main responsibilities. It maintains balance between water and salts and removes excess water and nitrogenous wastes from the body.

There are certain soft bodied animals like sponges, coelenterates and echinoderms in which there are no special excretory organs.

The nitrogenous waste and water are removed from body surface.
