What does 'more efficient industries' mean in economic unions?

• A. Countries produce everything domestically
• B. Trade barriers are removed completely
• C. Tariffs increase
• D. Countries specialize in what they do best and avoid overlapping production

Answer: (D)

Focusing on which industries are most productive within a union relies on specialization. When countries coordinate and trade freely inside the union, each country can concentrate on producing goods where it has a real advantage—using its resources, technology, and skills more efficiently. By avoiding duplicate production across multiple nations, resources are allocated where they generate the most output, which lowers costs and boosts overall economic efficiency. That’s why the statement about countries specializing in what they do best and avoiding overlapping production is the best description of what “more efficient industries” means in an economic union. Producing everything domestically ignores the gains from specialization; removing barriers entirely describes trade policy more broadly rather than the efficiency outcome within the union; and increasing tariffs would raise costs and hinder efficient allocation of resources.
