• A. Physical
• B. Biological
• C. Class
• D. Trace

Answer: (D)

The main idea here is recognizing a category of evidence defined by tiny, often microscopic, amounts of material found at a crime scene. This type, called trace evidence, covers both physical and biological material, as shown by examples like a strand of hair, a fingerprint, DNA, a drop of blood, pollen, or gunshot residue. The key is the small quantity, which can still be informative because such trace materials can transfer between people and objects and be analyzed to link a suspect to the scene or to narrow down possibilities. Physical evidence is a broad umbrella for nonliving materials, and biological evidence refers specifically to living or once-living material; neither emphasizes the small quantity aspect as precisely as trace evidence does. Class evidence relates to characteristics that point to a group rather than a specific source, whereas trace evidence highlights the tiny amounts that can still be linked to a source through careful analysis.
