What was the main difference between china's two revolutionary movements?

I hope this Helps : )

Explanation:

On October 1, 1949, Chinese Communist leader Mao Zedong declared the creation of the People’s Republic of China (PRC). The announcement ended the costly full-scale civil war between the Chinese Communist Party (CCP) and the Nationalist Party, or Kuomintang (KMT), which broke out immediately following World War II and had been preceded by on and off conflict between the two sides since the 1920’s. The creation of the PRC also completed the long process of governmental upheaval in China begun by the Chinese Revolution of 1911. The “fall” of mainland China to communism in 1949 led the United States to suspend diplomatic ties with the PRC for decades.

i think the answer is b.
