Final answer:
Adam Smith's economic theories underpinning capitalism and advocating free trade were influenced by the Enlightenment and were counter to mercantilism. They predated the Communist Manifesto, which critiqued the capitalist system Smith helped establish.
Step-by-step explanation:
Smith's ideas could have been influenced by all of the options provided except the Communist Manifesto. Adam Smith, a key figure of the Enlightenment, promoted economic theories that laid the foundation for capitalism, opposing the restrictive practices of mercantilism and advocating for free trade and minimal government interference in markets. His seminal work, The Wealth of Nations, was written well before the emergence of industrialization and the publishing of the Communist Manifesto by Karl Marx and Friedrich Engels, which occurred in the mid-19th century and critiqued the capitalist system that Smith's ideas helped to establish.
