问题如下：
Forward commitments subject to default are:
选项：
A. forwards and futures.
B. futures and interest rate swaps.
C. interest rate swaps and forwards.
解释：
C is correct.
Interest rate swaps and forwards are over-the-counter contracts that are privately negotiated and are both subject to default. Futures contracts are traded on an exchange, which provides a credit guarantee and protection against default.
A is incorrect because futures are exchange-traded contracts which provide daily settlement of gains and losses and a credit guarantee by the exchange through its clearinghouse. B is incorrect because futures are exchange-traded contracts which provide daily settlement of gains and losses and a credit guarantee by the exchange through its clearinghouse.
A为什么不对？怎么理解 谢谢
