Answer 2

Hey Mate!!

Option A Devonian is correct.

Palaeozoic era is also called as “era of ancient life”. It is divided into six periods, which are namely Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian period. Ordovician period (505-430 million years ago) is marked by appearance of first vertebrates and fungi as well as major extinction of marine species. Silurian period (430-410 million years ago) marked by origin of jawed fishes, wingless insects and terrestrial vascular plants. This makes options B and D incorrect as fishes originated in Silurian period. Devonian period (410-360 million yrs ago; 'age of fishes') is marked by origin of amphibians and diversification and dominance of fishes on earth.

Hope this helps you!!
