Like other analytical tools, arc mapping is useful for ___________.

Arc mapping is particularly useful for analyzing the sequence of events in fire investigations. This analytical tool allows investigators to visually represent the progression and relationship of various events during the fire. By mapping out the sequence, investigators can gain insights into how the fire started, how it spread, and the dynamics involved in its development. This visual representation can help establish timelines and patterns that are crucial for understanding the incident as a whole.

While documenting witness statements, identifying witnesses, and collecting physical evidence are all important components of a fire investigation, they do not directly relate to the specific function of arc mapping. Arc mapping focuses more on the graphical representation and analysis of events rather than the collection of verbal or physical evidence. Thus, its primary function is to facilitate a clearer comprehension of the sequence of events, making option B the most accurate choice in this context.
