Which of the following best describes the concept of opportunity cost in the context of comparative and absolute advantage?

Opportunity cost is the idea that when you choose one option, you are giving up the benefits of another option. In the context of comparative and absolute advantage, it helps us understand why countries or individuals make certain choices in production. For instance, if a country can produce both cars and computers, but it is much better at making cars than computers, it has an absolute advantage in car production. However, if the country gives up fewer computers than another country to produce more cars, it has a comparative advantage in cars. So, opportunity cost helps us see the trade-offs involved in making these choices, guiding us to make decisions that maximize benefits.
