问题如下：
If a revision of Falana’s key facts and assumptions regarding Sabonete and the SPP were to occur, which would least likely result in the plan’s funded status deteriorating?
选项：
A.Salary growth rate raised to 3.6% B.Decline in short-term interest rates C.Average participant age raised to 48
解释：
B is correct. A decline in short-term interest rates is least likely to affect SPP’s funded status, because liabilities are discounted using 10-year rates. In addition, it is highly likely that only a small proportion of the fixed-income assets would be invested in short-term assets given the long-term nature of the liabilities.
A is incorrect. A higher salary growth rate increases the projected liabilities and thus negatively affects the funded status of the SPP.
C is incorrect. Average participant age affects the date and timing of future benefit payments. If the average participant age increases, withdrawals from the plan will occur sooner, causing the present value of future withdrawals from the SPP to increase, resulting in a negative impact on its funded status.
请问B怎么理解，麻烦老师详细讲下，谢谢。
