The most accurate conclusion about the reason the Chinese population supported Deng Xiaoping after analyzing the changes to China’s economy in the 1980s and 1990s is:
They hoped he would reverse Mao Zedong’s policies.
Deng Xiaoping implemented economic reforms that shifted China from a command economy to a more market-oriented one, which contrasted with Mao's strict communist policies. Many people supported these changes as they sought economic growth and improved living standards following the economic hardships under Mao's rule.
