How would the u.s. government most likely react to a slump in the economy?

I believe the answer is ower taxes to make it easier for consumers and businesses to spend money. Option D is correct.

By lowering taxes, the government make the companies lower their price while maintaining same amount of profit (since profit is the main goal of any company in the market). Thus consumptions will be boost, employment increased, the economy fostered by criculating the money, and investment lured.
