Explanation:

Class evidence is evidence that can be associated with a group, not an individual. A footwear impression from a commonly - worn shoe can be associated with a class of shoes of that type. DNA is individual evidence. White powder residue could potentially be identified to a specific substance but without more context, and a torn piece of paper that fits with a notebook is individual evidence as it can be linked to a specific notebook.

Answer:

a footwear impression left by a suspect's shoe that has been worn for a year
