In the context of international trade, which of the following scenarios best illustrates the principle of comparative advantage considering factor endowments and economic efficiency?

Comparative advantage is the idea that a country should specialize in producing goods that it can make more efficiently than other goods, even if it can produce everything better than another country. For example, imagine Country A can produce both cars and wheat, but it is much better at making cars. Meanwhile, Country B is less efficient at making both but is relatively better at producing wheat. If Country A focuses on making cars and Country B focuses on wheat, both countries can trade and end up with more of both goods than if they tried to produce everything on their own. This way, each country uses its resources more efficiently, benefiting from their unique strengths.
