Final answer:
A Totalitarian Regime was responsible for killing citizens during the natural climatic phenomenon of 1958 to 1961, fitting the Great Chinese Famine under Mao Zedong's rule. (option C)
Step-by-step explanation:
The natural climatic phenomenon from 1958 to 1961, known as the Great Chinese Famine, occurred during the leadership of Mao Zedong in the People's Republic of China, which was a totalitarian regime. The government's policies, particularly the Great Leap Forward, led to disastrous agricultural practices, contributing to widespread famine and the deaths of millions of Chinese citizens. The totalitarian nature of the regime, characterized by centralized control, suppression of dissent, and state-directed economic planning, played a significant role in exacerbating the crisis. The government's refusal to acknowledge and address the extent of the famine further intensified the humanitarian catastrophe.
The responsible form of government for the killing of citizens during the 1958-1961 social crisis was a Totalitarian Regime, exemplified by the policies of Mao Zedong's administration in China, which contributed to the severity of the Great Chinese Famine and its tragic consequences.
