Which of the following best describes an action that can cause a whistle-blowing system in place in the organization to fail? a. Management is slow to act on reports of suspected fraud. b. An extensive code of ethics is in place and on file in order to answer employee inquiries. c. The organization requires employees to report all suspicious activity. d. The employee suspecting fraud reports directly to his/her supervisor's manager.

A whistle blowing is an act of exposing an activity or informing the authority of any private or public organization that an illegal or unethical action has been carried upon in the organization. The person who inform the wrongdoing at the organization to the media or to the superiors internally are known as whistle blowers.

But when the management or the authority of the organization does not take the whistle blower seriously and delays on the report to take necessary action against the fraud, it causes a failure of the whistle blowing system in the organization and the wrong doers take advantage of it.

Hence the correct option is (a).
