The answer to that question is letter B. Fief or what we call feudum in Latin is an important element in feudalism. This process occurs when an overlord or vassal grants property of rights over a chosen individual. Usually these inheritances are in a form of property of lands. An overlord or vassal gives something to a chosen individual because they are entitled to a fee or a fealty. Giving a fealty is something an overlord or vassal would do to pay off services or allegiance given to them.
