The answer is D. The Cultural Revolution, formally the Great Proletarian Cultural Revolution, was a sociopolitical movement in China from 1966 until 1976. Launched by Mao Zedong, then Chairman of the Communist Party of China, its stated goal was to preserve Chinese Communism by purging remnants of capitalist and traditional elements from Chinese society, and to re-impose Mao Zedong Thought (known outside China simply as Maoism) as the dominant ideology within the Party.
In the violent struggles that ensued across the country, millions of people were persecuted and suffered a wide range of abuses including public humiliation, arbitrary imprisonment, torture, hard labor, sustained harassment, seizure of property and sometimes execution. A large segment of the population was forcibly displaced, most notably the transfer of urban youth to rural regions during the Down to the Countryside Movement. Historical relics and artifacts were destroyed and cultural and religious sites were ransacked. Hope this helps! ~ Autumn :)
