Answer: (B)

GSR stands for Gun Shot Residue, which refers to the tiny particles that are expelled when a firearm is discharged. This residue can settle on the hands, clothing, or surfaces near the firing location, and it is an important element in forensic investigations. The presence of GSR can help establish whether an individual has fired a weapon, handled a firearm, or was in close proximity to a discharged firearm. Understanding GSR is crucial for forensic technicians because it is often used as evidence in criminal cases, particularly in incidents involving gun violence. Tests such as the paraffin or swab tests can detect these residues on a person's hands and are commonly utilized in shooting investigations, as well as in determining the timeline of events surrounding firearm-related offenses.
