Answer 1

Biodiversity or biological diversity alludes to various living forms, usually expressed as the number of species in an area, or the number of hereditary types in a region. The term biodiversity was advocated by Edward Wilson. It is the variety of life at all degrees of natural association inside an animal type (genetic diversity), among species diversity and comparative diversity among communities and ecosystems (ecological diversities).

Complete answer:
A vulnerable species is a type which has been categorized by the International Union for Conservation of Nature as liable to become endangered unless the conditions that are threatening its survival and reproductive improve. Vulnerability is basically brought about by natural surroundings misfortune or devastation of the species home.
Rare species are the species which have a small population. Many of these move into the endangered or vulnerable category if the negative variables influencing them keep on working. Examples of rare species are the Himalayan brown bear, Fennec fox, Wild Asiatic buffalo and Hornbill.
The great Indian bustard (Ardeotis nigriceps) or Indian bustard is a bustard which is found in the Indian subcontinent. It is a bird with an even body and long bare legs, which gives it an ostrich-like appearance, this fledgling is among the heaviest of the flying feathered creatures. Once common on the dry plains of the Indian subcontinent, as not many as 150 people were assessed to get by in 2018 and the species is critically endangered by hunting and loss of its living space. These birds are regularly found related in a similar environment as blackbuck. Because of decimation of regular territory and poaching, it has become a rare animal variety.

Hence the correct answer is OPTION(D)

Note: Human intervention is to a great extent answerable for biodiversity misfortunes. A significant reason for worry in the current occasions is the sensational rate at which biodiversity is being lost. Significant human activities, for example, habitat loss and, over abuse and exploitation, contamination, intensive farming is answerable for the quickened paces of species extinction.
