Correct answer: A. To draw the boundary between India and Pakistan
Explanation: The Radcliffe Commission was created to draw the boundary between India and Pakistan at the time of Partition, so option A is correct. Sir Cyril Radcliffe chaired the boundary commissions that worked in 1947, especially for Punjab and Bengal. The line was drawn during a very short and difficult period, when political control was ending and the future territories of India and Pakistan had to be separated. The boundary affected villages, districts, transport routes, property, and family connections.
The other choices describe unrelated actions. The commission did not impose the salt tax, form the Indian National Congress, or create armies for princely states. Its work is remembered through the term “Radcliffe Line,” which refers to the Partition boundary. Although the boundary decision itself was administrative, it had profound human consequences because many people had to cross it and leave their homes. Thus option A gives the commission’s principal task.
