The correct answer is: b) Establishing British dominance in the region.
The Anglo-Nepalese War (1814-16) was a conflict between the British East India Company and the Kingdom of Nepal. The war was fought over control of the Himalayan region. The British were victorious, and the Treaty of Sugauli was signed in 1816. The treaty gave the British control of Nepal’s Terai region, and it also established British dominance in the region.
Sikkim was a small kingdom located in the Himalayas. It was a vassal state of Nepal, and it was ruled by the Chogyal. The Anglo-Nepalese War had a significant impact on Sikkim. The war weakened Nepal, and it allowed the British to establish dominance in the region. This benefited Sikkim, as it meant that the British would protect Sikkim from Nepal.
The other options are incorrect. Option a) is incorrect because the Anglo-Nepalese War did not lead to the restoration of Sikkimese territory. Option c) is incorrect because the Anglo-Nepalese War did not reduce Bhutan’s influence. Option d) is incorrect because the Anglo-Nepalese War did not weaken the Chogyal’s power.
