This time, I'm going for a change! Not dddd47906!

What is one reason

A. It did not allow national religions.
B. it encouraged warfare among feudal lords.
C. It made laws and set up courts to uphold them.
D. It encouraged serfs to leave the manor.

My answer- A. I think that is why since they did not want any one interfering their religion, Christianity, and they didn't want anyone to destroy the Church.
