The correct answer is B) The only way to bring about a classless society is through a violent revolution.
Communists strongly believed that revolution led by the workers - proletariat - was necessary to achieve the change they needed. But Utopian Socialists were strongly influenced by Greek philosophers Plato and Aristotle and they believed that society would change by the education of its members. A revolution would go against everything they believed in since they defended a harmonic society.
