Overall, democracy is the best form of government, because it is morally the most justifiable, although democratic governments today can be improved.

The answer is A.
The feudal system would follow from the king down to the serfs.
What is confusing is the lords vs. knights. Lords will rule over knights and knights will rule over serfs.
Meaning the system kind of looks something like this:
King
Lord — Lord — Lord
Knight — Knight — Knight — Knight — Knight — Knight
And serfs
Hope this helps, have a great day!
