The correct option is A

A-3, B-1, C-2


Fishes and amphibians lay unfertilized eggs so fertilisation and development is external. In mammals both fertilisation and development are internal. But in reptiles and birds fertilisation is internal and development is external as they lay fertilized eggs.
