Correct Answer: Oxygenated blood

Solution : The correct option is O xygenated blood.

Haemocyanin present in the blood of prawns, octopuses, snails, and other creatures is blue. Prawns have an open-type blood circulatory system. Both veins and capillaries are absent. The arteries that carry pure blood from the heart split and divide into minuscule branches that flow freely in the hemocoel. As a result, even if the arteries carry mixed blood, the heart always contains oxygenated blood.
