The correct answer is C. In the first three decades of the 20th Century, Georgia cotton production was negatively impacted by the Boll Weevil.
The boll weevil is a beetle that is about six millimeters long, which feeds on the buds and flowers of cotton. By the 1920s it infected all the cotton production areas of the United States, greatly affecting the industry and the people who worked in the southern United States, specifically in the state of Georgia. It was not until the 1970s that the plague could be controlled, with the help of government control programs.
