问题如下：
The two-bond hypothetical portfolio’s immunization goal is to lock in a rate of return equal to:
选项：
A.
9.55%.
B.
9.85%.
C.
10.25%
解释：
B is correct.
Immunization is the process of structuring and managing a fixed-income portfolio to minimize the variance in the realized rate of return and to lock in the cash flow yield (internal rate of return) on the portfolio, which in this case is 9.85%.
为什么这道题选B不选A

YTM不就是内部收益率吗？
