Negotiations for free trade in china in the 19th century caused what reaction

Assuming that this is referring to the same list of options that was posted before with this question, the correct response would be the one having to do with these negotiations leading to rebellion in China, since many people were worried about unwanted western cultural influence. 

This is a tough one, as we all have out own opinions, but based on the answer choices, i'm going to say the answer is D- a procedure for enforcing rules. Hope this helps! :)
