Despite the opium outlaw, the British continued to bring the drug into China. This resulted in the Opium Wars which lasted from 1839-1842. The possibility of war was threatened by Lin (leader of China) during the early 1830's when he wrote a letter to Queen Victoria. However, Britain did not see this as a threat and ended up easily defeating the Chinese due to their strong naval forces. The Treaty of Nanjing ends the Opium Wars and results in China losing Hong Kong.

The answer is B. The Opium War.
