Which statement describes patent prints?

• A. They require chemical processing to be seen.
• B. They are invisible and must be lifted.
• C. They are easily smudged and disappear.
• D. They are visible to the naked eye without processing.

Answer: (D)

Patent prints are impressions that are already visible without any chemical enhancement, because they are made by substances like ink, blood, or oil transferring from a finger to a surface. This makes them easy to see with the naked eye right away, so no processing or development is needed to observe them. They can be photographed or preserved by lifting if desired, but their defining feature is immediate visibility. The other ideas describe latent prints, which are invisible until treated, or make assumptions about smudging, which aren’t the defining trait of patent prints.
