A non-emergency incident does not require an immediate response and no imminent threat exists. It is a non-critical situation that requires a(n):

The correct answer is that a non-emergency incident requires a public safety response. This is because, even though the situation is not critical and does not demand immediate action, a response from public safety officials is necessary to ensure that the issue is addressed appropriately.

Public safety responses can involve various forms of assistance, such as the dispatch of police, fire, or medical personnel, when it's needed to resolve an issue or assist the community without the urgency associated with emergency situations. This kind of response allows for the situation to be handled effectively without detracting from resources that are reserved for urgent matters.

In contrast, while options regarding non-emergency police response or immediate supervisor's attention may seem relevant, they do not encompass the broader scope of what a public safety response entails. Furthermore, stating that no action is necessary would downplay the importance of addressing the situation, even if it is not urgent; thus, ensuring that a public safety response is provided would be the most appropriate course of action.
