The correct option is C Fish
Cold blooded animals
Cold blooded animals are those animals who have body temperature fluctuations with changing environment. Example- fish.
Single circulation
The cold blooded animals have a 2−chambered heart containing one atrium and one ventricle. The deoxygenated blood is pumped from the ventricle to the gills for oxygenation.
The oxygenated blood is supplied to different parts of the body and the deoxygenated blood enters the atrium of the heart. This then passes to the ventricle.
Since the blood completes on a single circuit, this type of circulation is called single circulation.
