The correct answer is C) Over 18 million.
How many people were killed in Mao's China as a part of the Great Leap Forward? Over 18 million.
However, we have to clarify this. Most historians agree that an exact number can't be given. Most of them refer to an approximate number, from 15 to 50 million people.
Mao Zedong never thought that this Great Leap Forward would result in a major disaster and a big famine. The worst in the history of China. Mao's original idea had been to launch China into an industrial revolution to create factories and fabrics to modernize China. However, the result was the opposite.
