The event that led to the opening of trade ports in China was a) The Opium War.

Here are the steps that led to this:

1. In the mid-19th century, Britain was importing a significant amount of tea from China, but China was not importing nearly as much from Britain. This led to a trade imbalance.

2. To correct this imbalance, Britain began illegally exporting opium from India to China.

3. The Chinese government was not pleased with the widespread addiction to opium among its citizens and took steps to ban the opium trade.

4. This led to the First Opium War between Britain and China from 1839 to 1842.

5. China lost the war and as part of the Treaty of Nanking in 1842, they were forced to open up five ports to foreign trade.

6. This marked the start of the "Century of Humiliation" in China, a period of intervention and imperialism by Western powers and Japan in China.
