The correct option is C. Mercosur. Explanation of the Correct Answer Mercosur, or the Southern Common Market, is a regional trade bloc in South America that was established in 1991. Its primary aim is to promote economic cooperation and integration among its member countries, which include Argentina, Brazil, Paraguay, and Uruguay, with Venezuela's membership currently suspended. The organization focuses on reducing trade barriers, facilitating the free movement of goods, services, and factors of production, and fostering economic collaboration among its members. Key Features of Mercosur:

1. Trade Liberalization: Mercosur aims to create a common market by eliminating tariffs and other trade barriers among member countries.
2. Economic Integration: It encourages economic policies that promote cooperation in various sectors, including agriculture, industry, and services.
3. Political Cooperation: Beyond economic goals, Mercosur also seeks to enhance political dialogue and cooperation among its members.

Why the Other Options Are Incorrect A. European Union (EU): - The EU is a political and economic union of European countries, primarily focused on integration within Europe. While it promotes economic cooperation, it is not aimed at the Americas, making it irrelevant to the question. B. ASEAN (Association of Southeast Asian Nations): - ASEAN is a regional organization in Southeast Asia that promotes economic growth, cultural exchange, and political stability among its member states. Like the EU, it is not related to the Americas, thus making it an incorrect choice. D. African Union (AU): - The AU is a continental union consisting of 55 African countries, aimed at promoting unity and cooperation among African nations. Its focus is on the African continent, not the Americas, which disqualifies it as a correct answer. Summary of Key Points

• Mercosur is the correct answer as it specifically targets economic cooperation and integration among countries in the Americas.
• The European Union, ASEAN, and African Union are all regional organizations focused on their respective continents and do not pertain to the Americas.
• Understanding the geographical and functional scope of these organizations is crucial for identifying the correct answer in questions about economic groupings.

Revision Summary

• Mercosur promotes economic cooperation in South America.
• The EU, ASEAN, and AU focus on Europe, Southeast Asia, and Africa, respectively.
• Recognizing the regional focus of each organization helps in answering questions accurately.
• Economic integration is a key goal of Mercosur, distinguishing it from other groupings.
