Latent prints are prints that are not visible without processing.

• A. Latent prints are prints that are not visible without processing
• B. Latent prints are prints that are visible before processing
• C. Latent prints are prints that are created by ink or dust
• D. Latent prints are prints that are impossible to lift

Answer: (A)

Latent prints are fingerprints that are not visible to the naked eye and require processing to be seen. They’re formed from natural skin oils and sweat left on surfaces when a person touches something, so they aren’t obvious until developed with powders or chemical reagents. This is in contrast to patent (visible) prints, which are already seen because they’re made with substances like blood, ink, or dirt, and plastic impressions, which are actual indentations in soft materials. The statement captures the essential idea that latent prints are invisible until they’re processed, which is why processing steps are needed to visualize them.
