The correct answer is "B":
Karl Marx was a Prussian Economist and the founder of the concept of Socialism. A political current that coexists with capitalism nowadays. Marx stated that capitalism will inevitably lead to conflicts between "the proletariat" or working class and "the burgoise" or ruling class. The working class will become aware of their status, question the current status quo and eventually engage against the working class to form a new order which he names Socialism.
Marx stated that before Capitalism, hunter-gatherer societies lived in Anarchy, as they were not guided by any central ruler but were self-governed groups.
