The answer is A. Whistleblowers.

Whistleblowers disclose unethical issues occurring within their organization when they realize that they undertake harmful activities that may interfere with people's rights. Whistleblowing aims to provide a transparent and safe workplace that complies with all the required regulations and considers people's rights. Whistleblowers face huge dilemmas and high risks of losing their jobs. However, they are covered by whistleblowing laws if such employees believe that their actions are of public interest, and if they view their disclosure as displaying the past, present, or future possibility of issues such as criminal offenses, endangering of people's health and safety, damage to the environment, and failure to comply with the law.
