A. They became fragmented feudal states.

Explanation:

Frederick II ruled Sicily and Germany. He had ambitions to conquer and bring Italy under the control of his kingdom of Sicily.

In an attempt to rule Italy, Frederick II and the popes entered into a conflict. If Italy comes under the power of a single emperor, the influence of the Pope would diminish.

The cities in north Italy agreed and did not approve the rule of Sicily emperor. This led to Frederick having several small battles with the north Italian cities. He won the small battles but ended up facing defeat in the war.
