In budget trade-offs, what is the correct description of opportunity cost?

• A. The benefits foregone by not choosing the next best alternative.
• B. The total cost of the budget program.
• C. The tax revenue foregone.
• D. The interest payments on debt.

Answer: (A)

Opportunity cost is the value of the next-best alternative you give up when you make a choice. In budgeting, resources like money and time are limited, so funding one program means you have fewer resources for other programs that could have provided benefits. That foregone benefit is exactly what opportunity cost measures—the benefits you sacrifice by not choosing the next best option. It isn’t the total cost of implementing a program, which would count all expenses, nor is it inherently the tax revenue foregone or the interest payments on debt, which are financing or revenue considerations rather than the alternative you forgo.
