问题如下：
which of the following statements about the failure of LIBOR is incorrect?
选项：
A.LIBOR was constructed from a survey of a small set of banks reporting non-binding quotes rather than actual transactions.
B.The banks can manipulate LIBOR submissions
C.Before the GFC, there were a lot of actual transactions underpinned the submissions for the longer LIBOR tenors.
D.due to regulatory and market efforts to reduce counterparty credit risk in interbank exposures, banks have also tilted their funding mix towards less risky sources of wholesale funding (in particular, repos).
解释：
C is correct
选项C的描述错误。正确的描述为：before the GFC, very few actual transactions underpinned the submissions for the longer LIBOR tenors.
就是关于libor,其实他的实际交易量不大？有点疑惑如下：
1.libor目前国内银行一半定价都是根据libor来（虽然最近慢慢在改），但是感觉这个libor实际交易量应该占比还是份额最大的吧？
2.如果说libor不够大，是因为otc市场的交易比银行间libor的量大的多吗？有具体的数据比例可以参考吗？
