问题如下：
After further review of the composition of each of the funds, Cécile makes the following notes:
- Note 1: Aschel is the only fund of the three that uses leverage.
- Note 2: Rosaiso is the only fund of the three that holds a significant number of bonds with embedded options.
Based on Note 2, Rosaiso is the only fund for which the expected change in price based on the investor’s views of yields to maturity and yield spreads should be calculated using:
选项：
A.
convexity
B.
modified duration.
C.
effective duration.
解释：
C is correct. Rosaiso is the only fund that holds bonds with embedded options. Effective duration should be used for bonds with embedded options. For bonds with embedded options, the duration and convexity measures used to calculate the expected change in price based on the investor’s views of yields to maturity and yield spreads are effective duration and effective convexity. For bonds without embedded options, convexity and modified duration are used in this calculation.
