The correct answer is D. What is the rate of unemployment, is a macroeconomic question.

Unemployment refers to the decline in job opportunities in a particular area or region. Unemployment is considered a macroeconomic factor because it drives the rate of production, consumption, and distribution. When there is a high unemployment rate, the consumption, production, and distribution rates will be low. When there is a low unemployment rate, the consumption, distribution, and production rates will be high. Macroeconomics mostly focuses on the three macroeconomic factors (production, distribution, and consumption).
