Which event in 1947 reshaped South Asia's political landscape and created enduring religious tensions and migrations?

• A. Partition of British India into India and Pakistan.
• B. Unification of India and Pakistan.
• C. The founding of the first Indian republic.
• D. A major agricultural reform program.

Answer: (A)

In 1947, the Partition of British India into two states—India and Pakistan—redefined South Asia’s political map and set off large-scale religious-based migrations. The division created a Muslim-majority Pakistan and a Hindu-majority (though diverse) India, prompting millions to move across new borders along religious lines, often amid violence and chaos. This event also left lingering tensions between the two nations, contributing to disputes over borders, minorities, and later conflicts such as those over Kashmir. The other options don’t produce this combination: unification never occurred, the founding of the Indian republic happened later and concerned internal constitutional changes rather than cross-border separation or mass displacement, and a major agricultural reform program addresses economics more than the political restructuring and sectarian migrations seen with partition.
