Which one represents an expected indicator of incendiary fire behavior?

An expected indicator of incendiary fire behavior is characterized by inconsistent ignition sources. This relates to the nature of incendiary fires, which often involve multiple points of ignition that do not follow a typical pattern of accidental fires. In cases of incendiary activities, a fire may start in various locations or appear to have been ignited by different means, showing a lack of coherence in ignition sources. This inconsistency is a key factor that fire investigators look for as a sign that the fire was deliberately set, as opposed to being caused by a singular external factor.

Understanding the behavior of incendiary fires helps in distinguishing them from other types of fires, which might have more predictable patterns of ignition and spread. The presence of multiple, varying ignition sources raises suspicion and warrants a closer investigation into the fire's causes and potential motives behind it.
