Solution

The correct option is C Two chambered
Fishes have two chambered heart i.e., one auricle and one ventricle. There is mixing of pure and impure blood and hence they are cold blooded. Amphibians and reptiles (except crocodile) have three chambered heart. Crocodiles, birds and mammals have a four-chambered heart. Thus, the correct answer is option B.
