Answer 1

Hint: Animals of phylum Chordata having spinal cord are classified as vertebrates. The Vertebrates mainly include Aves (Birds), Mammals, Reptiles, Amphibians, and Fish.

Complete answer:
Due to continuous destruction caused by humans to nature, the species of many animals are facing threats and are left with only a few species. According to data given by the zoological survey of India, we can conclude that the minimum species in the case of vertebrates is that of Mammals in India

Option(A): Since among the vertebrates Mammals have the lowest number of species that is 410 species in India.

Option(B): According to data obtained in the year 2019, India has a total of 1349 species of birds out of which 78 species of birds are endemic to India.

Option(C): According to data obtained by the zoological survey of India, There are a total of 518 species of reptiles out of which more than half species are that of snakes.

Option(D): The number of Amphibian species in India is 472 and about 236 species of amphibians are endemic.

Hence, the correct answer is option (A)

Note: 1.According to various surveys and data it is found that vertebrates comprise only 5.7 percent of total organisms and the remaining 94.3 percent are the invertebrates.
2.The data about various species in India are mainly collected and maintained by the zoological survey of India (ZSI) which was established on 1 July in the year 1916.
