Option 4, Durand Line, does not demarcate any part of India`s international boundary. Durand Line is the border between Afghanistan and Pakistan. It was drawn by Sir Mortimer Durand in 1893 to separate British India from Afghanistan. This line served as the boundary between the two countries after Pakistan`s formation in 1947. It is not related to India`s international boundary.
On the other hand, the other options mentioned in the question do demarcate parts of India`s international boundary:
1. Radcliffe Line: It was drawn by Sir Cyril Radcliffe during the partition of India in 1947 to separate India and Pakistan. It demarcated the borders of the two countries, primarily in the Punjab region.
2. McMahon Line: It is the boundary line between China and the Indian state of Arunachal Pradesh. It was drawn by Sir Henry McMahon in 1914.
3. Sir Creek Line: It is the disputed boundary between India and Pakistan in the Rann of Kutch region. It is a marshy area and has been a subject of ongoing territorial disputes between the two countries.
