Which of the following is NOT an example of macro variable?

Land

The correct answer is Option 1: land

The macro variables are those that represent the economy as a whole rather than specific individual components. Land is a factor of production and typically considered as a microeconomic variable rather than a macroeconomic variable.

The other options, economic growth, inflation, and unemployment, are all examples of macroeconomic variables as they represent aggregate economic phenomena that affect the entire economy.
