The correct answer is: A. Kongka La Pass
The Kongka La Pass is a high mountain pass in the Ladakh region of India. It is located on the Line of Control (LoC), the de facto border between India and China. The pass is at an elevation of 5,460 meters (17,910 feet) and is the highest point on the LoC.
The Kongka La Pass was the site of a major military standoff between India and China in 1962. The standoff began when Indian troops crossed the LoC and entered Chinese-controlled territory. The Chinese responded by sending troops to the area, and the two sides engaged in a series of skirmishes. The standoff ended with the signing of a ceasefire agreement in November 1962.
The Kongka La Pass is a popular destination for trekking and mountaineering. The pass is also a major trade route between India and China.
