Which term describes a situation that is immediately likely to result in serious harm without intervention?

The term that best describes a situation that is immediately likely to result in serious harm without intervention is "Imminent Danger." This term is used to indicate a threat that is not only approaching but is also urgent, meaning that action needs to be taken swiftly to prevent harm or injury. Imminent danger implies that the risk is immediate and requires an urgent response to mitigate potential consequences.

In contrast, "Deadly Force" refers to a specific level of force utilized in self-defense situations where there is an imminent threat of death or serious bodily injury, but it does not encompass all cases of immediate danger. A "Peaceful Demonstration" does not indicate any level of danger, as it generally refers to a gathering intended for expression in a non-violent manner. The term "Feasible" pertains to the practicality of an action, rather than the immediacy of a threat. Thus, "Imminent Danger" accurately captures the essence of a situation requiring immediate intervention to prevent significant harm.
