The question is about matching cities with their correct countries. Here`s the breakdown of each option:

Option 1: Salamanca is indeed in Spain. It is famous for its Renaissance architecture and is home to one of the oldest universities in the world.

Option 2: Cannes is actually not in Italy, it is situated on the French Riviera and is in France. Thus, option 2 is incorrect, making it the correct answer to the question.
