Answer:
D) British gunboats forced China to make major concessions
Explanation:
The British managed to come out as the victorious side in the two Opium Wars with China. The superior military, including the gunboats, made China to make major concessions. This led to strengthening of the British influence in East Asia, and also they were the ones that controlled the opium trade. The result of this was a lot of profit for the British Empire, but a hard hit for China, which needed more then a century in order to recover economically from this and get back on track as a strong economic power.
