Answer 1

The correct option is A Coelom

• Coelom is the principal body cavity in most animals located between the intestinal canal and the body wall. In developed animals, it is lined with mesothelium.
• The cockroach is a coelomate animal but its coelom is greatly reduced in the adults. The coelom is represented by the cavities of the reproductive organs. The body cavity is filled with hemocoel which is filled with blood. The hemocoel is related to the blood vascular system.
