问题如下：
Which of the following curves is best described as a series of yield-to-maturity on zero-coupon bonds?
选项：
A.
Yield curve
B.
Spot curve
C.
Par curve
解释：
B is correct.
By definition, spot curve is a series of yield-to-maturity on zero-coupon bonds.
考点：收益率曲线
解析：题目问通过一系列零息债券的持有期收益率（YTM），构建出来的是哪种收益率曲线图。Zero-Coupon Bond的折现率YTM，就是Spot Rate，所以选项B正确。
零息债券不就是价格等于面值吗
