请问44题答案为什么选B

All of the following could help to reduce the credit exposure on a set of derivative transactions except: A daily mark-to-market of transactions B netting agreements with the counterparty C collateral and other credit enhancements D early termination agreements 老师，您好，我错选了C，因为haircut越大，exposure越小，那么信用增级了，haircut变小了，exposure变大了，哪里理解的不对。 另外，D选项，我们之前的break clause 是减小敞口的一种技术，D说的不就是这个技术吗？

Bank A, which is AAA rated, trades a 5-year interest rate swap (semi-annual payments) with Bank B, which is rated BBB. Because of Bank B's poor credit rating, Bank A is concerned about the 5-year exposure it is going to run because of the swap deal. Which of the following measures help mitigate Bank A's credit exposure to Bank B? Ⅰ.Negotiate a CSA with Bank B and efficiently manage the collateral management system Ⅱ.Execute the swap deal as a reset swap wherein the swap will be marked to market every six months Ⅲ.Execute the swap deal with a break clause in the third year Ⅳ.Decrease the frequency of coupon payments from semi-annual to annual 老师，是A付coupon给B吧？那减少付款频率，不是降低exposure，为什么第四个不对呢
