Quizplus · Accepted Answer

An infrared microspectrophotometer and a polarizing microscope are both commonly used instruments to view and identify the properties of fibers found at a crime scene. A stereoscopic microscope can also be used, but it may not provide sufficient magnification for identifying the generic class of individual fibers. Therefore, options A and C only are the best choices as they are both specialized instruments for fiber analysis.
