问题如下：
Which of the following statements best portrays the full implementation of post- financial- crisis regulations in the OTC derivatives market?
选项：
A.Transactions are no longer private.
B.Most transactions need to be reported to regulators.
C.All transactions must be cleared through central clearing agencies.
解释：
B is correct. With full implementation of these regulations in the OTC derivatives market, most OTC transactions need to be reported to regulators. A is incorrect because although under full implementation of the regulations information on most OTC transactions needs to be reported to regulators, many transactions retain a degree of privacy with lower transparency. C is incorrect because although under full implementation of new regulations a number of OTC transactions have to be cleared through central clearing agencies, there are exemptions that cover a significant percentage of derivative transactions.
