Organisms with a circulating body fluid that is distinct from the fluid that directly surrounds the body's cells are likely to have

The correct answer is- a closed circulatory system.

Explanation:

There are two types of circulatory system, open circulatory system and closed circulatory system. In an open circulatory system, the blood flows through cavities and no blood vessels are present here from which blood can flow. Open circulatory system is found in invertebrates.

In organisms which have closed circulatory system, blood vessels are present in which blood flows and reaches to different cells in the body.

So in organisms that have closed circulatory system blood or body fluid does not directly surround the body cells as in the open circulatory system. So the right answer is-a closed circulatory system.
