Option C) The open circulatory system is common to mollusks and arthropods. Open circulatory systems pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood. Cockroaches and silverfish have an open circulatory system. They don't have any blood vessels.
