Remark
Interesting question. Since Boxing day (December 26) is a big deal in Canada (almost like black Friday in the US) I'll take some time on this. I've never really known the background.
Comments.
D was definitely something the Boxers (so named because they did exercises that they thought would make them immune to bullets) didn't like very much. There was constant tension between European influences and the ruler Qing emporers on the throne at the time.
B is also true. Many Chinese Christians were killed during the Boxer rebellion. The Boxers must not have liked their presence and influences very much.
A is kind of tricky. They did resist, but it was more on the grounds of the way the industrialization was brought in. If it were me, I'd include it. Others may not. If you do include it, don't be surprised if you get it wrong.
I don't think C is correct. The Opium Wars (about 40 to 50 years earlier were more about Opium.
Two additional facts:
1. The Chinese agreed to pay 330 million in reparations. The 8 countries that were paid returned the money.
2. The Chinese resisted but lacked modern weapons to fight an effective war.
