Which one of the following groups of animals belongs to the category of endangered species?

The group consisting of the Great Indian Bustard, Musk Deer, Red Panda, and Asiatic Wild Ass represents species that are classified under various threatened categories in India. The Great Indian Bustard is critically endangered, while the Red Panda and Musk Deer are listed as endangered due to habitat loss and poaching [2]. The Asiatic Wild Ass is found in the Rann of Kachchh and is categorized as near-threatened or endangered depending on specific regional assessments [4]. Other options include species like the Blue Bull (Nilgai), Cheetal (Spotted Deer), and Hanuman Langur, which are generally classified as 'Least Concern' under the IUCN Red List because they have stable populations and wide distributions across the Indian subcontinent [4]. Therefore, Option 1 is the only group where all members are recognized as high-priority threatened or endangered species requiring intensive conservation efforts [3].
