D) Trained fingerprint crime scene investigator: It is the most prepared person to perform the task.
B) Profilometer: It is a measurement instrument used to measure and create a surface profile.
C) Inverted Cone: A normal fire would develop a V-pattern because they move up and out creating a pattern similar to the letter "V". While abnormal fires like the one from the example, which was created with a fire accelerant such as gasoline create an inverted cone pattern. It does this because it starts as a normal fire but because of the strength gave with the accelerant, it can no longer move up, only out.
