The correct answer is option B.
In Europe, during the middle ages, the government and society were based on the Feudal system. Feudalism flourished between 9th and the 15th centuries. In this system, a piece of land was granted to the people for service. This system was in a way based on the hierarchy in which the king was on the top and who was followed by the Bishops (church leaders), Barons and nobles (high ranking nobles), Lords and Knights (the local Manors), and peasants and serfs (slaves) at the bottom.
