Intervening during an audit involving ethical wrongdoing (Option 1) and negotiating a settlement of an employee claim for personal damages (Option 4) represent significant ethical risks if exhibited by an organization's board. These actions could indicate attempts to influence or undermine the audit process and the fair handling of ethical issues, leading to potential conflicts of interest and compromising the integrity of the organization's governance processes. Discussing periodic reports of ethical breaches (Option 2) and authorizing an investigation of an unsafe product (Option 3) are appropriate and responsible board actions that do not pose ethical risks.
