Answer: Individual Characteristics
Explanation:
Individual characteristics are the unique properties or makeup of a person which can be used to link an evidence under investigation to the person in question.
Handwriting investigators rely on the belief that each individual has a style of writing which is peculiar to them. As we develop our writing skills from childhood, in time, we develop our own style off writing which is inherent in us.
So when there is a questioned document, forensic experts compare the individual characteristics of the person's previous writings to the document under investigation.
