In which year was the Treaty of Sugauli, between the Gorkhas and the British, signed?

The correct answer is: D. 1815 AD

The Treaty of Sugauli was signed on 24 November 1815 between the British East India Company and the Gorkha Kingdom. The treaty ended the Anglo-Gorkha War (1814–1816) and resulted in the Gorkha Kingdom ceding much of its territory to the British.

The treaty was signed at Sugauli, a village in the present-day Indian state of Bihar. The British were represented by David Ochterlony, while the Gorkhas were represented by Amar Singh Thapa.

The treaty stipulated that the Gorkhas cede all of their territory to the east of the Kali River, including the Kathmandu Valley. The Gorkhas were also required to pay a war indemnity of 50 lakhs of rupees.

The treaty was a major blow to the Gorkha Kingdom. It resulted in the loss of much of its territory and its status as an independent kingdom. The treaty also led to the decline of the Gorkha power and influence in the region.

The treaty was controversial at the time, and it has been criticized by some historians for being unfair to the Gorkhas. However, the treaty was ultimately accepted by the Gorkhas, and it helped to establish peace and stability in the region.

The other options are incorrect because they are not the years in which the Treaty of Sugauli was signed.
