The correct answer is D. The socialist nature of the programs.
Critics of Franklin D. Roosevelt's New Deal argued that his policies were socialist. Socialism is a political and economic system which revolves around the idea that the means of production and resources in a society are owned by the community as a whole. In other words, the government would monitor the production and distribution of goods. This idea scared many Americans, as they felt that any socialist type program would lead to less individual freedoms. It was argued that FDR's programs were close to this, as the government started taking over/monitoring several institutions (like banks) during this time period.
