According to David Ricardo's theory of comparative advantage, which of the following scenarios best illustrates the concept of opportunity cost?

David Ricardo's theory of comparative advantage explains how countries or individuals can benefit from trade by specializing in the production of goods they can produce most efficiently. Opportunity cost is the value of what you give up when choosing one option over another. For example, if Country A can produce either 10 tons of wheat or 5 tons of corn, and Country B can produce either 4 tons of wheat or 2 tons of corn, the opportunity cost for Country A to produce 1 ton of corn is 2 tons of wheat. This means that by choosing to produce corn, Country A is sacrificing the chance to produce more wheat, which shows how understanding opportunity cost helps make better economic decisions. Thus, the scenario that illustrates comparative advantage is one where each country focuses on what it can produce at a lower opportunity cost compared to the other.
