Who was the president of Boundary Commission to delineate boundary between India and Pakistan?

Sir Cyril Radcliffe

The correct answer is Option 3 - Sir Cyril Radcliffe

The president of the Boundary Commission to delineate the boundary between India and Pakistan was Sir Cyril Radcliffe. He was a British lawyer who had no previous experience in cartography or boundary demarcation. Radcliffe was appointed to the commission by Lord Mountbatten, the last Viceroy of India, in June 1947.

The Boundary Commission was tasked with drawing a boundary between India and Pakistan that would divide the two countries along religious lines. Radcliffe was given five weeks to complete his task, and he worked under tremendous pressure. He was also faced with a number of challenges, including the fact that the two countries had overlapping claims to territory and that there were large populations of both Hindus and Muslims living on both sides of the proposed border.

On August 17, 1947, Radcliffe presented his award to Mountbatten. The award divided India and Pakistan into two separate countries, and it created the longest land border in the world. Radcliffe's award was controversial, and it led to widespread violence and displacement on both sides of the border.
