Solution

The correct option is A Tympanum represents the ear
In reptiles, external ear is absent; the ear is represented by a tympanum. Most reptiles have a three chambered heart, except crocodiles, which have a four chambered heart. Reptiles are poikilotherms (cold-blooded), and oviparous (egg-laying).
