The correct answer is D. Since the death of Mao Zedong, China has experienced the most success in economic growth and private ownership.
After Mao's death in 1976, Deng Xiaoping seized power and implemented a series of economic reforms, after which the Communist Party ceased to exercise governmental control over the personal lives of the citizens and the communes dissolved in favor of private lease. This shift in events marked the transition from a planned economy to a mixed economy with an increasingly open market environment, and the People's Republic of China adopted its current constitution on December 4, 1982.
President Jiang Zemin and Premier Zhu Rongji led the nation in the 1990s. Under their administration, China's good economic performance brought about 150 million peasants out of poverty and maintained an average annual GDP growth rate of 11%. The country formally joined the World Trade Organization in 2001 and maintained its high rate of economic growth under the presidency of Hu Jintao in the first decade of the 21st century.
