The correct answer is B.
Feudal system was based on manorialism, and governed economic relationships during the medieval era in Europe.
The privileged social groups, nobility and clergy, were landowners. They granted their fields to peasants, who could cultivate them for a living in exchange for becoming vassals to their lords, who had total rights over them. On the first hand, peasants had to pay "taxes" to their lords to be able to feed themselves from their fields, and had to obbey any of their orders. In turn, lords promised protection to their vassals, as they were powerful enough to have some military forces under their command.
The Hacienda system resembled some of these chacteristics, as the rich social groups were the landowners, while the poorest sectors worked for them in the hacienda fields and were totally dependent on the will of the landowners.
