)Answer:
The correct answer is letter "B": International trade allows a country to specialize in items that can be produced most efficiently in that country.
Explanation:
Adam Smith (1723-1790), David Ricardo (1772-1823) and Eli Heckscher (1879-1952) and Bertil Ohlin (1899-1797) jointly provided their thoughts on international trade each one with their own position. In common, they believed international trade allowed companies to specialize in the production of goods they were the best at so countries could export those goods while importing goods whose production was developed by other countries specializing in them.
In such a scenario, countries would approach an absolute advantage and maximum efficiency. Either theory assumed there were no trade barriers and that the factors of production cannot move between countries.
