Answer 1

The correct option is B Aves>Reptiles>Mammals>Amphibians

A total number of species in a particular class are being specified (on an Indian government portal) as :

Mammals: 423 species (7.81% of the worlds' total mammals)

Aves: 1,233 species (13.66% of world's total aves)

Reptiles: 526 species(5.7% of the world's total reptiles)

Amphibians: 342 species (5.05% of the world's total amphibians)

thus, arranged according to the number of species in decreasing order we find,

Aves>Reptiles>Mammals>Amphibians
