Opportunity cost is best described as?

• A. The cost of the next best alternative use of money, time, or resources when one choice is made.
• B. The total value of all goods and services produced domestically.
• C. The amount of taxes collected by the government.
• D. The price of a specific good in the market.

Answer: (A)

Opportunity cost is the value of the next best alternative you give up when you make a choice. It focuses on what you sacrifice in order to obtain something else. The description you’re looking at captures this idea by framing cost as the next best use of money, time, or resources when one option is chosen.

Think about it with a simple example: if you spend an hour studying for a test instead of working a part‑time job, the opportunity cost is the wage you could have earned in that hour (and any additional benefit from the work you gave up). If you have $20 and buy a book, the opportunity cost is what else that $20 could have bought or the value you’d have gotten from the alternative use of that money.

This concept isn’t the same as the total value of all goods and services produced in a country (that’s GDP), nor the amount of taxes collected, nor the market price of a single good. The right description specifically highlights the value of the next best foregone option when a decision is made.
