Q. Which line serves as the official international boundary between India and Pakistan?
Answer: Radcliffe Line
Notes: The Radcliffe Line, established in 1947, serves as the official international boundary between India and Pakistan. It was drawn by Sir Cyril Radcliffe and runs from the northern Line of Control to the southern Zero Point. The line was created during the partition of British India, which led to significant demographic changes and conflicts. The McMahon Line, in contrast, pertains to the boundary with China, while the Durand Line separates Pakistan from Afghanistan.
