What is the name of the disputed boundary between India and China?

Understanding the various boundary lines in South Asia is crucial for comprehending regional geopolitics. Disputed borders often lead to significant international tensions.

• The Line of Actual Control (LAC) is the correct answer. It is the demarcation line that separates Indian-controlled territory from Chinese-controlled territory in the Sino-Indian border dispute. Unlike a legally defined international border, the LAC is a de facto boundary.
• The Durand Line is the border between Afghanistan and Pakistan.
• The McMahon Line is a specific proposed boundary in the eastern sector of the India-China border, which China disputes, but the overall disputed boundary is referred to as the LAC.
• The Line of Control (LoC) is the de facto military control line between India and Pakistan in the former princely state of Jammu and Kashmir.
