Which type of complaint is conducted without revealing the complainant's identity?

The correct answer is that an anonymous complaint is one that is conducted without revealing the complainant's identity. This type of complaint allows individuals to express their concerns or report issues without the fear of retribution or the need for their identity to be disclosed. This is particularly important in scenarios where individuals may feel unsafe or hesitant to come forward, as it promotes a safer and more open environment for reporting misconduct or discrimination.

Unlike formal complaints, which typically require the complainant to identify themselves and provide detailed information, anonymous complaints prioritize confidentiality. Informal complaints may not necessitate anonymity since they often involve discussions that can be resolved without a formal procedure. Public complaints are those that are made known to wider audiences, thus clearly not being anonymous.

Overall, the structure of anonymous complaints serves to encourage reporting and creates an avenue for addressing issues while minimizing the risk to the complainant.
