Under Standard IV(C), Responsibilities of Supervisors, members and candidates should encourage their employers to provide clients with the firm's code of ethics. This practice effectively communicates the firm's commitment to ethical business conduct and prioritizing clients' best interests.

• Option B is incorrect because Standard IV(C) encourages, but does not require, firms to adopt a code of ethics. Adoption is voluntary but critical for establishing an ethical foundation.

• Option C is incorrect because Standard IV(C) recommends keeping the code of ethics distinct from compliance procedures. A standalone code should be clear, concise, and focus on general fiduciary principles without being overly detailed.
