What is the total value of a nation's annual output, used as an indicator of the level of economic activity in a country?

• A. Inflation
• B. Indirect tax
• C. Gross Domestic Product
• D. Interest rate

Answer: (C)

Gross Domestic Product is the total value of a nation’s annual output, representing everything produced within the country in a specific period. It serves as a broad measure of economic activity because higher GDP indicates more goods and services being produced and sold, signaling a larger or faster-growing economy. People often compare GDP over time to judge whether the economy is expanding or contracting, and they compare it across countries to gauge relative size and strength. GDP can be calculated in different ways—by summing spending on final goods and services (consumption, investment, government spending, and net exports), or by total income or production—and is often reported in real terms to strip out inflation so we can see genuine growth. The other options relate to price changes, tax receipts, or borrowing costs, not the overall level of production in an economy.
