Questioned handwritings and drawings can appear on which of the following?

Questioned handwriting and drawings can appear on various surfaces, and option B accurately reflects the diverse contexts in which they can be found. These surfaces include everyday locations and objects such as walls, mirrors, cars, and bodies. The presence of handwriting or drawings in these areas can be significant in a crime scene investigation, providing evidence that may link a suspect to a crime or provide insight into the actions or state of mind of individuals involved.

Other options suggest limitations on where questioned writings can be found, which does not align with the reality of forensic investigations. For instance, personal journals and notebooks are just one type of potential evidence, and professional documents and electronic formats also represent only a fraction of where this type of writing may be found. In criminal investigations, it is important to be open to a broader range of evidence sources, which includes unconventional surfaces and materials, as indicated in option B. This understanding is critical as investigators seek to gather all relevant information that may contribute to understanding a crime scene comprehensively.
