Which of the following statements best defines comparative advantage?

Comparative advantage is the ability of a person, business, or country to produce a good or service at a lower opportunity cost than others. This means that they can make that product more efficiently compared to other options available to them. For example, if Country A can produce cars more efficiently than wheat, while Country B can produce wheat more efficiently than cars, each country should focus on what they do best. By doing this, they can trade with each other and both end up with more cars and wheat than if they tried to produce both on their own. This concept shows how specialization and trade can benefit everyone involved.
