The correct answer is C because falsely claiming a professional designation violates both Standard IV(A) - Loyalty and Standard I(D) - Misconduct.

• Standard IV(A) - Loyalty: This standard pertains to employment-related matters, requiring members to act in the best interest of their employer. Falsely claiming a designation can harm the employer by misrepresenting the member's qualifications, potentially damaging the employer's reputation.

• Standard I(D) - Misconduct: This standard prohibits professional conduct involving dishonesty, fraud, or deceit. Falsely claiming a designation is inherently dishonest and reflects poorly on the member's integrity and professional reputation.

Thus, the action violates both standards.
