The correct answer is A) A socialist who called for the overthrow of the capitalist system.
In his book, the Communist Manifesto, Karl Marx describes how a capitalist system will result in a struggle between the working class and ruling class. He felt that the disparity in wealth between these two classes will result in a violent overthrow of the capitalist system. In his mind, this system would be replaced with a socialist system. The socialist system would revolve around economic equality (aka no social classes) and government control of the economy.
