问题如下：
An asset manager wants to hedge the interest risk of a bond position with a 5-year key rate exposure of $9.84. A hedge instrument that has a corresponding 5-year key rate exposure of 4.12 per $100 of face value is avaliable, the amount of face value would be used to hedge is close to:
选项：
A.$41.87
B.$65.54.
C.$238.83.
D.$299.83
解释：
C is correct
考点：Key Rate ‘01s and Durations
解析：
(4.12/100) ×f=$9.84
f=$238.83
我看提问回答中有写“题目的意思是每100面值的对冲用的债券可以带来4.12的key rate的变化”，那4.12的变化是利率变动多少带来的变化？这里可以理解为duration吗？
