The correct option is C
Karl Heinrich Marx was a Prussian communist philosopher, economist, sociologist, journalist, intellectual and militant, and in his vast and influential work covers different fields of thought in philosophy, history, political science, sociology and economy; although he did not limit his work only to research, since he also ventured into the practice of journalism and politics, always proposing in his thought a union between theory and practice. Together with Friedrich Engels, he is the father of scientific socialism, modern communism, Marxism and historical materialism. His best known writings are the Manifesto of the Communist Party (co-authored with Engels), The Capital and The Eighteenth Brumaire by Luis Bonaparte.
