Final answer:
The correct answer is 'd. net exports, household spending, government spending,' as these are the components that contribute to total GDP. The answer also clarifies examples of items included in GDP and those that are not based on market value and final goods.
Step-by-step explanation:
The groups that contribute to the total GDP (Gross Domestic Product) are consumer spending (consumption), business spending (investment), government spending on goods and services, and spending on net exports. Therefore, among the provided options, the one that reflects these components correctly is 'd. net exports, household spending, government spending.' It is important to note that net exports are counted as exports minus imports, so it's the net impact of a country's trade that contributes to GDP.
When considering the examples of what is included in GDP and what is not, it's worth noting that GDP aims to capture all final economic production which has a market value. So live services like hospital stays and child care provided by a licensed daycare are included, while improvements in life expectancy and unpaid care by a grandmother are not. The sale of new cars is included in GDP since it reflects current economic production, but the sale of used cars is not because it was already counted when the car was new. Finally, the iron going into the steel for a new fridge is included as part of the fridge's market value.
