Households supply the factors of production to firms in exchange for money; firms supply goods and services to households in exchange for money - best describes the role of households and firms in the circular flow model of the economy. The correct answer would be option C.
The circular flow model illustrates how money circulates in an infinite cycle from suppliers to households and back again. Money goes back and forth in an economy as workers spend their income on goods and services, first going from manufacturers to workers as wages, and then back to producers. It is possible to make the model more intricate by including factors that increase the money supply, such as exports and imports. A country's gross domestic product (GDP) which is also known as its national income, is the outcome of adding up all of these variables.
Governments and central banks can modify monetary and fiscal policy to enhance an economy by analyzing the circular flow model and its present effect on GDP.
