单选题 Frank, CFA, heads the research department of a large brokerage firm. The firm has many analysts, some of whom are subject to the Code and Standards. If Frank delegates some supervisory duties, which statement best describes her responsibilities under the Code and Standards?

A. Frank's supervisory responsibilities do not apply to those subordinates who are not subject to the Code and Standards.
B. Frank no longer has supervisory responsibility for those duties delegated to her subordinates.
C. Frank retains supervisory responsibilities for all subordinates despite her delegation of some duties.

【正确答案】 C

【答案解析】[解析] 本题主要涉及执业操守标准Ⅳ(C)(监督责任)的相关规定。无论弗兰克的下属是否受CFA协会道德准则与执业操守标准的约束，弗兰克均应履行执业操守标准Ⅳ(C)所规定的监督责任。因此，选项A是错误的。根据执业操守标准Ⅳ(C)的规定，会员可以将其监督责任委托其下属负责执行，但上述委托行为不能免除会员自身的监督责任。因此，选项B是错误的。
