Solution

The correct option is B Frog
Amphibians (frogs) and reptiles have three chambered hearts in which there are two atria and a single ventricle. But in reptiles crocodiles (four chambered) are the exceptions.
Amphibians and reptiles have incomplete double circulation in which the route of circulation of deoxygenated and oxygenated types of blood are not completely separate. The pure and impure blood are mixed in the single ventricle and pumped out to the body parts.

Birds (parrot) and mammals (whale), crocodiles also have four chambered hearts which have two auricles and two ventricles.
In these organisms, complete double circulation takes place in which there are two separate routes for the circulation of deoxygenated and oxygenated types of blood. The right atrium and right ventricle are involved in the circulation of deoxygenated blood to the lungs. The left atrium and left ventricle are involved in the circulation of oxygenated blood to the body parts.
