Explanation: The McMahon Line is a significant geographical boundary that separates Arunachal Pradesh, a state in northeastern India, from Tibet, which is an autonomous region of China. This line was established during the Simla Convention of 1914, a tripartite conference between British India, Tibet, and China. The primary architect of this line was Sir Henry McMahon, a British civil servant and diplomat, hence the name "McMahon Line."
The Simla Convention was an attempt to resolve the boundary dispute between British India and Tibet. The agreement defined the boundary between Tibet and British India, which included the northeastern region of India, now known as Arunachal Pradesh. The McMahon Line was drawn to establish a clear demarcation between the two territories, with the intention of preventing any future disputes over the region.
However, the McMahon Line has been a subject of controversy and dispute. China does not recognize the McMahon Line as a legitimate international boundary, arguing that the Simla Convention was not legally binding because it was signed without the consent of the Chinese government. This has led to ongoing territorial disputes between India and China over the region.
Despite the controversy, the McMahon Line remains the de facto boundary between Arunachal Pradesh and Tibet. It is an important geographical and political boundary that has significant implications for the territorial integrity and sovereignty of both India and China. Understanding the historical context and the significance of the McMahon Line is crucial for comprehending the geopolitical dynamics in the region.
In summary, the McMahon Line is the correct answer because it is the established boundary that separates Arunachal Pradesh from Tibet, as defined by the Simla Convention of 1914. The other options refer to different geographical boundaries or are not recognized as valid international borders, making them incorrect in the context of the question.
