C

D

Solution

The correct option is C Crocodile
  • Mostly all reptiles and amphibians have a three-chambered heart. 
  • Thus, cobra, tortoise and salamander have three-chambered hearts, where two atria and one ventricle is present. 
  • But crocodiles are exceptions to this characteristic and have a four-chambered heart irrespective of being a reptile. 
So, the correct answer is option D.
