The correct answer is B) Communism.
The new political ideology in the 1800s that suggested the workers owned the means of production, everyone has equal pay, and there is no competition was Communism.
Karl Marx and Frederic Engels were the two main authors who developed the ideas of Communism in the 1800s. This new economic philosophy established that it was the Proletarian, the workers, that had the right to own the means of production in a country because they were the ones who worked the land or in factories.
Communism completely opposed Capitalists ideas that supported free enterprise, free trade, competition, and the possibility of getting reach developing businesses.
