The correct answer is: a) Nyishi.
The Nyishi are an ethnic group native to the Indian state of Arunachal Pradesh. They are one of the largest tribes in the state, with a population of over 300,000. The Nyishi are known for their unique culture and traditions, including their tradition of hereditary chiefs known as ‘gaonburas’.
The gaonbura is the head of a village or group of villages. He is responsible for settling disputes, organizing festivals, and representing the village to the outside world. The gaonbura is usually chosen from among the most respected members of the village, and his position is hereditary.
The Nyishi believe that the gaonbura is a descendant of the first Nyishi ancestor, and that he has a special connection to the gods. They also believe that the gaonbura is responsible for the well-being of the village, and that he must be obeyed by all.
The gaonbura system is an important part of Nyishi culture. It provides a system of governance and social order, and it helps to maintain the unity of the tribe.
