c为啥错了

问题如下：

Cannan has been working from home on weekends and occasionally saves correspondence with clients and completed work on her home computer. Because of worsening market conditions, Cannan is one of several employees released by her firm. While Cannan is looking for a new job, she uses the files she saved at home to request letters of recommendation from former clients. She also provides to prospective clients some of the reports as examples of her abilities.

选项：

A.Cannan violated the Code and Standards because she did not receive permission from her former employer to keep or use the files after her employment ended.

B.Cannan did not violate the Code and Standards because the files were created and saved on her own time and computer.

C.Cannan violated the Code and Standards because she is prohibited from saving files on her home computer.

解释：

According to Standard V(C)-Record Retention, Cannan needed the permission of her employer to maintain the files at home after her employment ended. Without that permission, she should have deleted the files. All files created as part of a member's or candidate's professional activity are the property of the firm, even those created outside normal work hours. Thus, answer B is incorrect. Answer C is incorrect because the Code and Standards do not prohibit using one's personal computer to complete work for one's employer.
