单选题 Edwin, CFA, obtained a copy of a computerized stock selection model designed by a former MBA classmate who is a Wall Street analyst. After spending some time reviewing the program and making some adjustments, Edwin showed the new model to his supervisor. His supervisor said he did a great job and told Edwin to incorporate the new model in his next industry review. He called his old classmates for permission, and she told him to go head and use the model, which he did without reference to his former classmate. Edwin has:

A、 violated Standard Ⅰ (Ｃ) Misrepresentation.
B、 violated Standard Ⅲ (Ｅ) Preservation of Confidentiality.
C、 violated Standard Ⅴ (Ｂ) Communication with Clients and Prospective Clients.

【正确答案】 A

【答案解析】[解析] 本题主要涉及执业操守标准Ⅰ(C)(不当表述)的相关规定。
根据执业操守标准Ⅰ(C)的规定，在发表第三方或无来源的研究结果时，会员可以在不将该研究结果归入自己名下的前提下加以使用和公布。在本题中，尽管艾德文花费了一些时间对模型进行审查并相应进行了一些调整，从而使该模型更符合其雇主公司的要求，而且获得了模型原始作者的使用许可，但他仍应在模型中加注原始作者的姓名，而不能简单地将模型视为由其自己设计完成的。因此，本题的正确选项为A。
