The correct option is A Bentinckia nicobarica and red panda
The endangered plant is Bentinckia nicobarica and endangered animal is red panda (Ailurus Fulgens). Leopard and blackbuck are listed as endangered animals but the plants that are listed with them as a pair Cinchona and Banyan tree are not endangered species. So these options are not correct. Tamarind and Rhesus monkey are not endangered species. Rhesus monkey is listed as Least Concern in the IUCN Red List of Threatened Species in view of its wide distribution, presumed large population, and its tolerance of a broad range of habitats.
