D! Countries that specialize benefit from trading with each other. Since countries produce goods they have a competitive advantage in, this allows them to make the best use of their time and resources.
The third time is correct (D).
Each country has its peculiarities, its productive structure, natural resources and different human capital. Thus, each country can specialize in what has a comparative advantage of production, that is, in what it produces more efficiently than other countries.
If each country specializes in what it produces most efficiently, both can benefit from trade by exporting the produced product efficiently and by importing the products whose production efficiency is greatest in another country.
