Solution

The correct option is C two chambers
Fish heart is two chambered, consisting of an auricle and a ventricle. This heart receives deoxygenated blood from the entire body, except the gills. It is pumped to the gills for oxygenation, following which the oxygenated blood is pumped to the entire body. Since the heart receives only deoxygenated blood, it is called venous heart.
