Answer:
C) Households may save part of the additional income from the tax cut
Explanation:
When we consider the total household income there is always a major part that is spent, this is called propensity to consume. It is defined as the proportion of total income that consumers are willing to spend.
But propensity to consume doesn't include 100% of household income, there also exists the propensity to save. That is the exact opposite, is the proportion of our income that we will save for future use.
Luckily for us all, the propensity to spend is usually much higher than the propensity to save. We have to remember that private consumption represents nearly 70% of the nation's GDP.
What households save goes to investment in GDP. Investment is always needed but it represents future growth of the GDP while consumption represents current growth of the GDP.
