问题如下：
Darcy works as an investment manager in a large firm. When attending a cocktail party, Darcy met a research analyst, Atwood, who showed interest in switching job to Darcy's firm. Atwood told Darcy that he recently engaged in a merger of two local companies. There is a rumor that the two companies will merge, but no official information has been made public yet. If Darcy doesn't want to violate the Code and Standards, what should he do?
选项：
A.Ask Atwood to officially release the new information so the information can be traded on.
B.Send emails to all the clients of his firm about the new information so as to help them make investment decisions.
C.Add the relevant securities to the firm’s restricted trading list.
解释：
C is correct.
Based on Standard II(A) Material Nonpublic Information, if a firm has or may have material nonpublic information, securities should be added to the firm’s restrict list, C is correct. The infomation can not be traded on until it is disseminated to the market, both Atwood and Darcy are not allowed to disclose the information to others, A and B are incorrect.
基于准则II(A)重大非公开信息，如果公司有或可能获得重大非公开信息，那么相关的证券应该被放入限制性清单里。所以选项C正确。
相关信息在被公开之前不可以用来进行交易，Atwood和Darcy不可以披露这些信息给别人，所以选项A和选项B错误。
b错在哪里了都公开了也有错？
