Which regional bloc uses a single currency called the Euro in its euro area?

• A. Mercosur.
• B. European Union (EU).
• C. ASEAN.
• D. CAFTA-DR.

Answer: (B)

Currency integration within a regional bloc is what this question is about, specifically which bloc uses a single currency—the Euro—in its euro area. The euro serves as the official currency of the euro area, which is the group of European Union member states that have adopted the euro as their legal tender. While the European Union includes countries that haven't joined the euro, the euro area itself is a subset of EU members using one currency. The other blocs—Mercosur, ASEAN, and CAFTA-DR—do not operate with a single shared currency; they rely on multiple national currencies or other arrangements. So the regional bloc that uses a single currency called the Euro in its euro area is the European Union.
