Final answer:
A higher real interest rate results in less investment spending.
Step-by-step explanation:
The correct statement about investment spending is B. A higher real interest rate results in less investment spending. Interest rates play a significant role in determining how much investment a firm will make. Higher interest rates increase the cost of investment and reduce the incentive for businesses to invest in capital. On the other hand, lower interest rates stimulate investment spending as they reduce the cost of borrowing money for businesses.
