Answer:
D) France
Explanation:
1. Francs (which I'm assuming they're talking about the currency) is a monetary unit most commonly found in France, Switzerland, Belgium, and Luxembourg.
2. Great Britain uses pound sterling, The United States uses USD, Italy uses Euros, and France uses Francs.
Therefore, the correct answer is D) France.
(You could also tell that the setting is in France because both France and Francs have "Franc" in them.)
