Correct Answer: Fishes
Solution : The correct option is Fish.
A venous heart is generally found in fish. Fishes have a closed-loop circulatory system, which means that blood flows in a single loop throughout the body. The venous heart pumps the deoxygenated blood from the body to the gills, where it is oxygenated. The oxygenated blood then returns to the body.
