Solution

The correct option is B Three
The cockroach has an open type of circulatory system as the blood, or haemolymph, flows freely within the body cavity or haemocoel. The blood vessel is poorly developed and open into spaces. Visceral organs located in the haemocoel are bathed in the blood. The three main parts associated with the blood circulatory system are the haemocoel, heart, and blood. The number of chambers in the body cavity are three.
So the correct answer is 'Three'.
