The Treaty of Yandaboo (1826) concluded the First Anglo-Burmese War and played a role in:

The Treaty of Yandaboo was signed on 24 February 1826 between the British East India Company and the Burmese Kingdom of Ava. The treaty ended the First Anglo-Burmese War, which had lasted from 1824 to 1826.

One of the terms of the treaty was that the Burmese cede the Tenasserim Province to the British. This included the Jaintia Kingdom, which was located in the southern part of the province. The British annexed the Jaintia Kingdom in 1835.

The other options are incorrect because:

• Option b) is incorrect because the British did not expand into the Khasi Hills until after the Treaty of Yandaboo.
• Option c) is incorrect because Shillong was not established as a hill station until 1864.
• Option d) is incorrect because the Treaty of Yandaboo did not mention tribal uprisings.
