Answer:
The correct answer is A. Mao Zedong's formation of the Red Guards led to attacks on personal liberty in China.
Step-by-step explanation:
The Red Guards were a mass movement, composed mostly of university students and high school students in China, who were mobilized by Mao Zedong between 1966 and 1967, during the Cultural Revolution, against the elitist elements of society.
This movement was promoted and manipulated by Mao in a strategy of regaining power. To encourage its development, Mao closed high schools and universities from 1966 to 1972.
The Red Guards were the authors of terrible excesses, which ranged from the systematic destruction of heritage to public humiliation, confinement in reeducation camps and, in some cases, the execution of intellectuals.
