问题如下：
Hsu also selects the two floating-rate bonds issued by Varlep, plc given in Exhibit below. These bonds have a maturity of three years and the same credit rating.
To value Varlep’s bonds, Hsu constructs the binomial interest rate tree provided below:
The value of Bond #8 is closest to:
选项：
A. 98.116% of par.
B. 100.000% of par.
C. 100.485% of par.
解释：
C is correct.
考点：使用二叉树对浮动利率债券进行估值
解析：
题干要求是对Bond 8进行估值，注意Bond 8是一个具有利率底（Floored at 3.50%）的浮动利率债券，当Coupon低于3.50%时，Coupon需要调整到3.50.
如下图所示，Year 1由浮动利率决定的Coupon为3.00，但是由于存在利率底，所以取不到3.00，需要将Coupon调整到3.50。
