The correct answer is: d) All of the above
The arrival of the British in the 19th century marked a significant turning point in the history of Arunachal Pradesh. The British established colonial administration in the region, which led to a number of changes, including the introduction of Christianity and the transformation of tribal societies.
The British first came into contact with Arunachal Pradesh in the early 19th century. In 1826, the British East India Company signed a treaty with the Raja of Manipur, which gave the British control over the area that is now Arunachal Pradesh. The British did not, however, establish direct rule over the region until the late 19th century. In 1894, the British government created the North-East Frontier Agency (NEFA), which included Arunachal Pradesh. The NEFA was administered by the British Indian government from Calcutta.
The British presence in Arunachal Pradesh had a number of significant impacts on the region. One of the most important impacts was the introduction of Christianity. The British missionaries who came to Arunachal Pradesh converted many of the local people to Christianity. Christianity has had a profound impact on the culture and society of Arunachal Pradesh.
Another important impact of the British presence was the transformation of tribal societies. The British introduced new laws and customs to the region, which led to changes in the way that tribal people lived. For example, the British banned the practice of headhunting, which was a common practice among some tribal groups.
