Solution

The correct option is B Crocodile
The crocodiles are the only reptiles that have a 4-chambered heart. It is somewhat like birds, a unidirectional looping system of airflow within the lungs, but like other reptiles they are ectotherms. There are two auricles and two ventricle where the oxygenated and deoxygenated blood remains separated.
Therefore, the correct answer is option B.
