According to Karl Marx, the social relations that matter MOST in a capitalist system are

A) family and kin.
B) community bonds.
C) economic relations.
D) nationalistic bonds.

According to Karl Marx's theory of capitalism, economic relations are the primary social relations that matter. Marx believed that the capitalist system is driven by the pursuit of profit, and therefore economic relationships between capitalists (who own the means of production) and workers (who are employed to produce goods and services) are the most significant social relations. Marx believed that these economic relationships would ultimately lead to class conflict and the overthrow of the capitalist system.
