With respect to international trade,specialization means that

A) each country consumes what it produces.
B) labor is exported or imported in much the same way as other products.
C) most goods and services that are traded internationally are produced in only 1 or 2 nations.
D) each country consumes a small fraction of what it produces.
E) labor and other resources in a nation are used to produce the products and services for which they are best suited.

Specialization means that different countries or regions focus on producing the goods and services that they have a comparative advantage in, based on their available resources and technology. This allows for more efficient production, greater output, and lower costs, which can benefit all the trading partners involved. Therefore, labor and other resources in a nation are used to produce the products and services for which they are best suited, leading to more specialization and trade. Option A, D, and C are incorrect because they do not accurately define specialization in international trade. Option B is partially correct since labor can be traded internationally, but it is not the same as other products because it involves human beings with unique skills and preferences.
