问题如下：
Which of the following spreads is described in basis points over an actual or interpolated government bond?
选项：
A.G-spread
B.Z-spread
C.OAS-spread
解释：
A is correct.
G-spread is described as the basis points over an actual or interpolated government bond.
考点：yield spread
解析：题干描述的是G-spread的定义，G-spread是公司债的YTM和政府债券的YTM之差，故选项A正确。
谢谢
