The right answer is a d. command economy. As a result of the cataclysms of World War, Revolution, Civil War, and a Great Socialist Offensive, the Command Economy organized the material bases of social and political life in pursuit of a Utopian dream. The structure of capital, labor, and production, the location of economic activity, nature and structure of economic interaction, the nature and sources of innovation, and how the Russian people and elites understood both the nature and meaning, the goals and objectives, of economic activity, and how it should be organized and managed, were all fundamentally changed.
As part of Stalin's Five-Year Plan, the government set up a D) command economy, in which the government owned all industries, setting quotas favoring heavy industry over production of consumer goods.
