A. Snake
B. Turtle
C. Lizard
D. Crocodile
Check Answer
The correct answer is D. Crocodile.
Crocodiles are reptiles with a four-chambered heart, which is a characteristic feature of birds and mammals, but is relatively uncommon in reptiles. The four-chambered heart of the crocodile allows for a complete separation of oxygenated and deoxygenated blood, which is an adaptation that enables the crocodile to have a high metabolic rate and a high level of activity. Other reptiles such as snakes, lizards, and turtles have three-chambered hearts.
