Answer 1

The correct option is A Bony fish - amphibians - reptiles - birds

Evolution of vertebrates involves invasions of sea, land, and air. With over half of the vertebrate species being fishes, the swim bladders of the bony fishes forms the first group from which the others evolved. The pulmonary vein of the amphibians made them the next which was followed by the reptiles which are the first group of vertebrates to survive on dry land. Birds are thought to have evolved from the dinosaurs with feathered wings as adaptions for flight.
