Which of the following statements is correct under the Code and Standards?
选项：
A. CFA Institute members and candidates are prohibited from undertaking independent practice in competition with their employer.
B. Written consent from the employer is necessary to permit independent practice that could result in compensation or other benefits in competition with a member’s or candidate’s employer.
C. Members and candidates are prohibited from making arrangements or preparations to go into a competitive business before terminating their relationship with their employer.
解释：
B is correct.
Under Standard IV(A) –Loyalty, members and candidates may undertake independent practice that may result in compensation or other benefit in competition with their employer as long as they obtain consent from their employer. Answer C is not consistent with the Standards because the Standards allow members and candidates to make arrangements or preparations to go into competitive business as long as those arrangements do not interfere with their duty to their current employer. Answer A is not consistent with the Standards because the Standards do not include a complete prohibition against undertaking independent practice.
请问c为什么不对，不应该是在离职前不从事竞争业务吗
