为什么这句话是对的呀？
If Janice were to add a 10-year period certain option to her annuity, her income yield would be reduced when compared with not having the option, but it would be reduced by greater amounts the longer she waits to purchase the annuity.
这里是答案的解释
C is incorrect because Statement 3 is correct. The addition of a 10-year period-certain option to an annuity ensures that the carrier will make payments for at least 10 years. The probability of a 50-year-old person dying within 10 years is much lower than for an older individual, e.g., it is much more likely for an 80-year-old person to die within 10 years than a 50-year-old person to do so. It is more likely that the period-certain option would be invoked for the older person, meaning a much bigger decline in income yield compared to not having the period-certain option.
