The correct option is D The British wanted to foster disunity among Indians.
Though the British claimed that the division was for administrative convenience, there was plenty of evidence suggesting that the partition took place along religious lines. This led to disunity among Indians, making it easier for the British to carry out a "divide and rule" strategy. The Indian National Congress strongly opposed the partition. The local communities also boycotted the idea and burnt British goods to display their opposition. Rabindranath Tagore organised a successful event of Rakshabandhan between East and West Bengalis to prove the brotherhood between both sides.
