The correct answer is: Manas National Park.
Manas National Park is a national park in the Indian state of Assam. It is located in the foothills of the Himalayas, and is part of the Eastern Himalayan biodiversity hotspot. The park is home to a wide variety of wildlife, including tigers, elephants, rhinoceroses, and deer. It is also home to a number of endangered species, such as the pygmy hog and the golden langur.
Manas National Park was designated a UNESCO World Heritage Site in 1985. However, the park was severely affected by the Bodoland conflict in the 1990s. The conflict led to the displacement of many of the park’s animals, and the destruction of much of the park’s infrastructure.
In recent years, there have been efforts to rehabilitate Manas National Park. The park has been reopened to tourists, and a number of conservation projects have been initiated. However, the park is still facing a number of challenges, including poaching, deforestation, and climate change.
