The pairings that correctly match an organization with its function are:
- African Union: resolve conflicts in sub-Saharan Africa
- European Union: resolve border disputes in Western Europe
- COMECON: promote trade in Communist Eastern Europe
While the statements regarding the Commonwealth and the Warsaw Pact are insensitive to their true functions—the Commonwealth primarily focuses on fostering collaboration among member countries, and the Warsaw Pact was a collective defense treaty among Communist states— the other pairings effectively describe the respective goals of those organizations.
If we focus on your specific question of correct pairings rather than evaluating them for accuracy, we observe that the African Union, European Union, and COMECON align with their functions correctly.
