What concept explains the need to make choices in economics?

• A. Scarcity
• B. Demand
• C. Utility
• D. Opportunity Cost

Answer: (A)

Scarcity is the reason we must make choices in economics. Because resources like time, money, and materials are limited while wants are endless, people and societies have to decide how to use what’s available—what to produce, how to produce it, and who gets it. That need to choose and trade off one option for another is the core idea scarcity describes. When you pick one option, you’re giving up something else, which is why economists talk about the costs of choices. Demand, utility, and opportunity cost are important concepts that relate to these decisions, but scarcity explains why the need to choose exists in the first place.
