老师 请问63题怎么做？谢谢

Payment netting is the simple netting of cash flows due on the same day. Closeout netting occurs if there is an event of default, which would include an incidence of fraud. One of the shortcomings of clearinghouses, and closeout netting as well, is that the other party, in this case ABC, jumps to the head of the queue with its claim on Repo Co. to the possible detriment of others, particularly those outside the clearinghouse in general. Thus, only C is correct. 老师这个题的解析不是很明白，可以详细说一下嘛？
