What did most of the rulers of Italy (except Piedmont-Sardinia) have in common?

C. They resented Austrian rule.

B. They considered themselves "Italian".

A. They were either loyal to Austria or were not willing to go against Austria.

D. They wanted unification.

The correct answer is A. They were either loyal to Austria or were not willing to go against Austria. Many rulers in Italy at the time were either directly ruled by Austria or had strong political and military ties with Austria, making them loyal to the Austrian Empire and less willing to go against its rule. Piedmont-Sardinia, on the other hand, pursued a more independent and nationalist agenda, which eventually led to the unification of Italy.
