Correct answer: A. Displacement of millions and refugee problem
Explanation: The direct answer is A: displacement of millions and a refugee problem. The Radcliffe Line was drawn in 1947 to divide British India into parts of India and Pakistan, especially Punjab and Bengal. The line divided villages, homes, farms, roads and families. Because people feared violence or found themselves on the opposite side of the new border, millions crossed the boundary. They lost homes and property and needed food, shelter, medical help and rehabilitation. A is correct because mass migration and the refugee crisis were major human consequences of Partition. B is wrong because the salt tax belonged to an earlier colonial policy and was not caused by the Radcliffe Line. C is wrong because the Congress was founded in 1885. D is wrong because the Surat Split occurred in 1907. Exam cue: a new political border can create forced migration and refugee problems.
