What is opportunity cost?

• A. The value of the foregone alternative when choosing one option
• B. The total cost of all options considered
• C. The price of the chosen option
• D. The tax associated with a decision

Answer: (A)

Opportunity cost is the value of the next best alternative you give up when you make a choice. It captures the real trade-off in any decision, not just money you spend, but the benefits you miss out on by not taking the other option. The correct idea emphasizes what you sacrifice in terms of potential gains, time, or enjoyment, rather than the price you pay for the chosen item or any taxes.

For example, choosing to spend time on one project means the opportunity cost is the value of the other project you could have worked on, or the leisure you forewent. It’s about foregone benefits, not the total or explicit monetary costs.

The other ideas don’t fit because one describes the total cost of options, which isn’t what you actually forgo by choosing one path; another describes the price of the chosen option, which is a direct monetary cost but not the lost alternative; and a tax is unrelated to the decision’s foregone benefits.
