Final answer:
The countries that belong to both the European Monetary Union and the European Union, from the choices provided, are France and Italy, as they are both EU members and have adopted the euro.
Step-by-step explanation:
The question asks us to identify which pair of countries are members of both the European Monetary Union and the European Union. Among the options given, each pair contains at least one country that is not a member of the European Monetary Union (which uses the euro as its currency), such as the United Kingdom and Norway, which both retain their national currencies. Similarly, Switzerland is not a member of the EU or the eurozone. Sweden, while a member of the EU, also does not use the euro. Denmark is an EU member but has a formal opt-out from the euro. Therefore, by process of elimination and referring to the list of countries provided, we arrive at the answer:
France and Italy both belong to the European Union and have adopted the euro as their currency, making them members of the European Monetary Union as well.
