curriculum里面的volume 1 第118页 第27题：

According to the "Standards of Practice handbook", which of the following activities is least likely to breach a member's duty to a client?

A) Keeping incomplete proxy voting records. 

B) Failing to disclose all forms of manager compensation. 

C) Using soft dollar arrangements to pay firm management expenses. 

D) Disclosing confidential client information to the CFA Institute Professional Conduct Program. 

正确答案是D，但是我得问题是，前三项虽然有错误，但是也不是"duty to client"方面的错误阿。比如B选项，failing to disclose all forms of manager compensation 是duty to client的那一小点？

谢谢。6月要考试了，很急
