Which of the following is an effective means of measuring a nation’s economic health?

The correct answer is C. Gross domestic product.

Gross Domestic Product (GDP) measures the total value of all goods and services produced in a country over a specific time period. It is a comprehensive indicator of a nation’s economic performance and health, reflecting its economic activity and growth. In contrast, minimum wage, consumer goods prices, and estate taxes do not provide a complete picture of overall economic health.
