What term describes the wants and needs of consumers for products and services?

• A. Economy
• B. Public good
• C. Scarcity
• D. Demand

Answer: (D)

Demand describes the wants and needs of consumers for products and services and the amount they are willing and able to buy at different prices over a period. It’s not just wishing for something; it involves purchasing power and the choice to buy at various prices. When prices drop, more people can afford to buy, so quantity demanded rises; when prices rise, quantity demanded falls. This distinguishes demand from other ideas: an economy is the whole system of production and exchange, a public good is something everyone can use without exclusion, and scarcity is the real constraint of limited resources. So the term that fits best is demand.
