The correct answer is:

Karl Marx - all of history has been a struggle between classes of people.

Explanation:

Adam Smith (1723-1790) is best known as the father of modern economics, and by his concept "the invisible hand" in which he proposed that the markets should regulate without the intervention of the government, but instead by the laws of competition, demand and supply, also known as laissez-faire. The thought that government should control market is the opposite to his theory.

Robert Owen (1771-1858) was a businessman famous for his influence in utopian socialism. He believed that people are not responsible for their character and the way they behave; but the education and formation from the earliest years in human life are. Owen developed and entire system of education and social reformation in his company New Lanark mill, he worked to improve the quality of life of his workers and was greatly involved with them, this is why the statement is incorrect.

James Keir Hardie (1856-1915) was a Scottish socialist. Hardie was the first one to represent the working class in the British Parliament and the founder and leader of the Labour Party. Since Hardie was a socialist that spent his life advocating for the working class, the statement is wrong.

Karl Marx (1818-1883) was German philosopher, economist and sociologist, that wrote with Friedrich Engels the famous book "The Communist Manifesto"; Marx's theories have great impact in Communism, because he stated that the problem of mankind is the struggle of classes and that capitalism is what creates this struggle, Marx believed that Capitalism would inevitably be substituted by Socialism, and eventually society would fall under Communism, which means common ownership and no social classes.
