Answer: A.
Mary Ann's conduct "is a violation of PMI’s Code of Ethics and Professional Conduct."
Explanation:
The Project Management Institute (PMI) expects Project Management Professionals (PMP) and PMP aspirants to abide by the Code of Ethics. An applicant applying for a PMP exam has to sign the PMP candidate agreement and Release form. In signing the agreement, the applicant agrees to abide by the Code.
The Code states that members and aspirants of PMI must;
• Act responsibly,
• Have respect for themselves and for others,
• Act fairly and,
• Be honest in their dealings.
Therefore by yelling at the representative, Mary Ann is in violation of PMI’s Code of Ethics.
