Answer;

A. Gas exchanges takes place by diffusion.

B. It is an open system.

Explanation; Most molluscs and arthropods have an open type of circulatory system. 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.
