One way the Revolt of 1857 impacted regions like Arunachal Pradesh was through:

Spread of anti-British sentiment among tribes
Influx of missionaries
Rapid economic development

The correct answer is: a) Increased British focus on consolidating control over frontier areas.

The Revolt of 1857, also known as the Indian Rebellion of 1857, was a major uprising in India against the rule of the British East India Company. The revolt began in Meerut on 10 May 1857 and spread to other parts of India, including Arunachal Pradesh.

The British responded to the revolt by increasing their focus on consolidating control over frontier areas like Arunachal Pradesh. This included building forts, roads, and railways, and stationing troops in the region. The British also increased their efforts to collect taxes and to recruit soldiers from the local population.

The increased British presence in Arunachal Pradesh had a significant impact on the region. It led to the displacement of many people, the disruption of traditional ways of life, and the introduction of new diseases. The British also introduced Christianity to the region, which had a major impact on the local culture.

The Revolt of 1857 had a lasting impact on Arunachal Pradesh. It led to the region becoming more closely integrated with the British Empire, and it also contributed to the development of a sense of Indian nationalism.
