Which of the following is NOT a stakeholder in a project?

C is the correct choice because a stakeholder in a project is defined as anyone who has an interest in or influence over the project's outcome. This includes individuals who can affect, or are affected by, the project in any way.

Individuals influencing the project, people interested in its outcome, and team members collaborating on it all have direct or indirect stakes in the project. In contrast, someone who is completely detached from the project has no interest or influence regarding its execution or outcome and thus does not qualify as a stakeholder. Understanding this distinction is crucial for identifying who should be involved in the project discussions and decision-making processes.
