Which of the following is an example of trace evidence?

Trace evidence refers to small, often microscopic materials that can be transferred from one location or object to another during the commission of a crime. This type of evidence is crucial in forensic investigations because it can provide valuable links between suspects, victims, and crime scenes.

Microscopic materials like hairs and fibers serve as prime examples of trace evidence. These items can be gathered from a variety of surfaces and may be present in such small quantities that they might go unnoticed without careful examination. Forensic experts can analyze these materials to determine their origin and potentially connect them to a suspect or victim, making them essential in the investigative process.

On the other hand, large pieces of furniture are too substantial to be considered trace evidence, as they do not fall into the category of small or microscopic materials. Consumables such as food and liquids may be involved in a crime but are generally not classified as trace evidence due to their nature and the way they are handled. Electronic records, while they can provide crucial information, are also not categorized as trace evidence, as they do not involve the physical transfer of small materials between surfaces or entities.
