Solution

The correct option is B Both assertion and reason are true but reason is not the correct explanation for the assertion
All reptiles have a three chambered heart, except the crocodile, alligators which has a four chambered heart. All other members of Reptilia have three chambered hearts with an incomplete septum in the ventricle. Crocodiles have a four chambered heart because the septum is complete resulting in the formation of a four chambered heart. Hence, it is an exception in reptiles with a four chambered heart. So, both assertion and reason are true but reason is not the correct explanation for the assertion.
