Which of the following is NOT a category of evidence?

The choice identifying "personal evidence" is correct because it is not a recognized category of evidence within forensic and legal frameworks. In criminal investigations, the classification of evidence typically includes physical evidence, documentary evidence, and direct evidence.

Physical evidence encompasses tangible items that can be collected and analyzed, such as fingerprints, weapons, or clothing. Documentary evidence refers to any written materials that can support a case, including contracts, emails, or photographs. Direct evidence is information that directly supports the truth of an assertion without requiring inference, such as eyewitness testimony or video recordings showing a crime taking place.

The absence of "personal evidence" as a category underscores the importance of differentiated classifications in legal processes, ensuring that each type of evidence serves a specific function in a case.
