The correct answer is: a) Intanki National Park.
Intanki National Park is a protected area in Nagaland, India. It is located in the Changlang district of the state, and covers an area of 1,980 square kilometers. The park is home to a variety of wildlife, including the endangered Hoolock Gibbon.
The Hoolock Gibbon is a species of ape that is found in the forests of Southeast Asia. It is a black ape with white cheeks and a long tail. The Hoolock Gibbon is an endangered species, and its population is declining due to habitat loss and hunting.
Intanki National Park is an important habitat for the Hoolock Gibbon. The park provides the ape with a safe place to live and breed. The park also helps to protect the Hoolock Gibbon from hunting.
