Which scenario would involve someone discovering a fire?

The scenario where someone discovers a fire is best represented by the situation involving the last person at the point of origin. This individual is typically the first to see the fire as it begins or is actively burning. Their presence at the point of origin signifies that they might witness the symptoms of a fire, such as smoke or flames, making them integral to any fire investigation as they can provide crucial information about the early stages of the fire incident.

In contrast, the last person to see the victim alive would not directly involve the discovery of the fire itself, as their focus would be on the victim rather than the fire. The person discovering the victim may not necessarily discover the fire at the same time; their priority is the victim’s condition instead. Firefighters extinguishing the fire, while they may see the fire in its active state, are performing a task rather than discovering the fire for the first time. They typically arrive once the fire has already been reported or detected, moving to manage and eliminate the threat.
