Correct Answer: cockroach and silverfish
Solution : The correct option is cockroach and silverfish
Cockroaches and silverfish have an open circulatory system. This type of circulatory system is characterized by the circulation of hemolymph (a fluid similar to blood) in open spaces called hemocoels. The heart pumps hemolymph into the aorta, which then delivers it to the hemocoel. The hemolymph flows through the body cavity, reaching all the organs and tissues, and then returns to the heart through a series of openings called ostia.
