To determine which group contributes to total GDP, we can refer to the components of GDP, which are typically represented by the equation:
\[ \text{GDP} = C + I + G + (X - M) \]
Where:
- \( C \) = Consumer spending (household spending)
- \( I \) = Investment (including capital goods)
- \( G \) = Government spending
- \( X \) = Exports
- \( M \) = Imports
Based on this equation, the valid components that contribute to total GDP would include:
- Household spending (C)
- Government spending (G)
- Net exports (which is exports minus imports, represented as \( (X - M) \))
From the responses provided, the correct answer that directly includes these components is:
net exports, household spending, government spending
This captures components of GDP as defined by the standard formula.
