The description which best matches feudalism is C. a tiered social structure where members of the lower class served those of the tier above. Nobles who had a lot of land would often hire those people below them to work for them, and in return they would often get some commodities. A is incorrect because feudalism has nothing with feuds, or fights between people. B and D are incorrect because the army and the religion weren't really in charge of anything during the Medieval times.
