According to Karl Marx, the mode of production that precedes capitalism is

Explanation

The question is asking about the mode of production that came before capitalism according to Karl Marx. Karl Marx was a philosopher and economist who had a significant impact on the development of socialism and communism. The question gives four options to choose from - Communalism, Feudalism, Mercantilism, and Socialism.

Communalism is a way of organizing society where resources are shared equally among members of a community. Feudalism, on the other hand, is a system of government where a lord gives land to a vassal in exchange for loyalty and military service. This vassal then gives a portion of the land to a tenant in exchange for labor and loyalty. Feudalism was the dominant mode of production during the Middle Ages.

Mercantilism is an economic system where a country's power is measured by its wealth, and wealth is measured by its accumulation of precious metals like gold and silver. It was popular in Europe during the 16th to the 18th century.

Socialism is a system of government where the means of production are owned and controlled by the state or the people. In socialism, resources are distributed equally among the members of society.

According to Karl Marx, the correct answer is Feudalism. This is because Marx believed that history was shaped by the struggle between different classes of people. Feudalism was a system where the ruling class (the lords) owned the means of production (the land) while the working class (the peasants) worked the land in exchange for a portion of the harvest. Marx argued that this system created a class struggle between the lords and the peasants and that this struggle eventually led to the rise of capitalism.

Therefore, the correct option is Option B - Feudalism.
