which statement?

C. China must violently resist foreign countries efforts to control the country.

Explanation:

The Chinese Boxer Rebellion occurred between the years 1899 and 1901 and was propagated by a secret society known as the Boxers who incited the Chinese peasants to rise up against the perceived exploitation of China by foreign powers such as Britain, France, Germany and other European countries.

They believed that China should resist the foreigners by any means necessary including by violence. They showed this by embarking on a violent campaign during the Rebellion to chase all Foreign powers from China and eventually got the support of the Government.

The Rebellion ended when a Multinational force defeated the rebellion and forced China to make concessions.
