On the occasion of the World Environment Day, 2021, which one of the following was declared as a National Park in India?

On the occasion of World Environment Day, June 5, 2021, the Assam government declared Raimona National Park as the state's sixth national park [1]. Located in the Kokrajhar district within the Bodoland Territorial Region (BTR), Raimona is part of a contiguous forest patch that includes the Manas National Park and the Phibsoo Wildlife Sanctuary in Bhutan. It is renowned for being a habitat for the Golden Langur, an endangered primate. Shortly after this declaration, Dehing Patkai was also notified as the seventh national park of Assam. In contrast, the other options provided—Orang, Dibru-Saikhowa, and Nameri—were established as national parks much earlier, with Orang being upgraded to a national park in 1999 and the others in the late 1990s [2].
