单项选择题
Which of the following statements about the relationship between interest rates and the demand for and supply of money is most accurate Interest rates affect:（）
A. the supply of money only.
B. both the demand for and supply of money.
C. the demand for money only.
答案
参考答案：C
解析：
Interest rates only affect the demand for money. With higher interest rates, the opportunity cost of holding money increases, and people hold less money and more interest-earning assets. Monetary authorities determine the supply of money. Therefore, the supply of money is independent of the interest rate.
