Answer:
c. Karl Marx
Explanation:
Within Karl Marx's ideas, he argued that communism was the objective of socialism. Humanity would have to undergo a series of steps to be able to evolve from a liberalist society, to a socialist one and then reach communism, where the class division was totally eliminated.
These steps include a revolution of the attacked (dominated classes) and the acceptance of the dominant races to leave the power to change it for the equitable treatment among all.
