Step-by-step explanation:
The direct answer to the question is C:
The evidence at the scene of an incident, such as a fire, should remain untouched until an investigator arrives to assess and collect it. This is a crucial step to ensure the integrity of the investigation. Firefighters are first responders who play a vital role in preserving the scene of an emergency. When it comes to a fire, firefighters may come into contact with potential evidence while performing their duties. The best practice is to disturb the scene as little as possible to avoid contamination or loss of evidence that may be crucial to the subsequent investigation. It is essential for firefighters to maintain the scene in the condition it was found to allow fire investigators to effectively analyze the evidence.
Any changes made to the scene can compromise the investigation and may lead to incorrect conclusions about the cause or nature of the fire. This is why the correct response is to keep evidence untouched, which means to avoid moving, altering, or interfering with any potential evidence until it can be properly documented and collected by an investigator specializing in fire-related incidents.
