The Revolt might have made the British more cautious about:

Expanding their influence in Sikkim
Interfering in Sikkim's internal affairs
Trusting local rulers in the Himalayan region
All of the above

The correct answer is: d) All of the above

The Indian Rebellion of 1857, also known as the Sepoy Mutiny or the Indian Mutiny, was a major uprising in India against British rule. The revolt began on 10 May 1857 at Meerut, and spread rapidly to other parts of northern and central India. The rebels were motivated by a variety of factors, including religious and economic grievances, as well as resentment of British rule.

The revolt was ultimately unsuccessful, but it had a profound impact on British policy in India. The British government abolished the East India Company and took direct control of India. The British also made a number of changes to their policies in India, in an effort to prevent future uprisings.

One of the changes that the British made was to be more cautious about expanding their influence in Sikkim. Sikkim was a small kingdom in the Himalayas, which had been under British protection since 1817. The British had been gradually increasing their influence in Sikkim in the years leading up to the revolt, but the revolt made them more cautious about doing so.

The British were also more cautious about interfering in Sikkim’s internal affairs. The British had previously intervened in Sikkim’s affairs on a number of occasions, but the revolt made them more reluctant to do so. The British were concerned that any interference in Sikkim’s affairs could lead to another uprising.

Finally, the revolt made the British more cautious about trusting local rulers in the Himalayan region. The British had previously relied on local rulers to maintain order in the Himalayan region, but the revolt made them more wary of doing so. The British were concerned that local rulers could not be trusted to keep order, and that they might even support an uprising against British rule.

In conclusion, the Indian Rebellion of 1857 made the British more cautious about expanding their influence in Sikkim, interfering in Sikkim’s internal affairs, and trusting local rulers in the Himalayan region.
