问题如下：
Basel II. 5 introduced the incremental risk charge (IRC) to further mitigate regulatory arbitrage. Chandler thinks that the incremental risk charge(IRC) recognizes the expected shortfall risk, because the amount of loss potential in the tail is important. Is he right?
选项：
A.Yes, he's right, and interest rate risk can also be recognized by IRC, because if the interest rate goes down, it means a huge loss for the bank.
B.No, he's wrong. It should be jump-to-default risk, because once a default happens, the bank will have an immediate and severe loss.
C.No, he's wrong. It should be exchange rate risk, because the uncertainty of exchange rate will have an impact on the bank.
D.Yes, he's right.
解释：
B is correct.
考点：the incremental risk charge
解析：
IRC识别的两种风险类型分别为：(1)credit spread risk; (2) jump-to-default risk.
loss potential risk和jump to default risk说的不是一个意思吗
