The nominal risk-free rate is best described as the sum of the real risk-free rate and a premium for:
选项：
A.maturity.
B.liquidity.
C.expected inflation
解释：
C is correct.
The sum of the real risk-free interest rate and the inflation premium is the nominal risk-free rate.
实际无风险利率和通货膨胀溢价之和就是名义无风险利率。
那是不是就是说 real rate=real risk-free rate呢
