B. Protect those who lived on the manor
C. Take an oath of chivalry
D. Provide personal and military service to the king
Correct answer choice is:
D. Provide personal and military service to the king
Step-by-step explanation:
In feudalism land grants and titles were given in as a gift or present for loyalty and military service. Fewer nobles were regarded to work as knights, whereas more nobles were regarded to protect military bases. Beneath the nobles were the knights and below them the peasants. Feudalism is basically a set of exchanges, simply give and take rule. Loyalty was given by the nobles to the King, knights were appointed for the duty of the king's protection, and peasants used to serve the food.
