(B) To earn money that could finance Britain's imports of tea and other goods from China.
Britain exported opium from India to China to earn silver/money, which was then used to pay for tea and other Chinese goods imported into England.

The passage states that "the British in India began exporting opium to China and took tea from China to England." This implies the opium trade generated the funds needed to buy Chinese tea. Option B correctly captures this trade-finance purpose. The other options introduce ideas (Indian farmer incomes, trade surplus correction, replacing indigo) not supported by the source passage.
