Answer:
The correct answers are:
B-Loyalty and obedience were valued traits.
C-Power belonged to the king and nobles.
F-Peasants paid taxes for protection from enemy nobles and knights.
Step-by-step explanation:
In a feudal system it was very difficult for someone to move between social classes. Also, people did not typically resist the King as they were seen as the 'natural' leaders and in many cases, chosen by God.
Also, the Kings did not grant land based on education. Lands and vassals were made based on the of military power that could be sent to the King when in need.
Apart from that, for feudalism to work, Loyalty and Obedience were valued. The whole system was controlled by the powerful Kings and local noble families who held a lot of power. Peasants should pay taxes to the nobles and local knights for protection and to work on the land.
