Which category includes weapons, bullets, and gunpowder residue analysis?

• A. Impression Evidence
• B. Firearms and Ballistics Evidence
• C. Biological Evidence
• D. Digital Evidence

Answer: (B)

Firearms and ballistics evidence. This category focuses on the examination of firearms, ammunition, and related residues to determine their involvement in a crime. It covers identifying the weapon, matching bullets to a barrel through rifling marks, linking cartridge cases to a firearm via tool marks, and analyzing gunpowder residue to infer firing or contact conditions. It also includes tests like gunshot residue analysis and trajectory studies to place a shooter. This makes it the right fit for analyzing weapons, bullets, and gunpowder residues. In contrast, impression evidence deals with marks left on surfaces by objects, biological evidence covers DNA and bodily materials, and digital evidence involves electronic data.
