Which option is not one of the three recognized types of prints?

• A. Digital
• B. Latent
• C. Patent
• D. Plastic

Answer: (A)

The key idea here is how fingerprints are categorized by their physical form at the scene. There are three recognized types: latent prints, which are hidden and require powders or chemicals to reveal; patent prints, which are visible impressions left by substances like ink, dirt, or blood; and plastic prints, which are three‑dimensional impressions made in soft materials such as clay, soap, or wax. Digital, while it relates to the image or recording of a fingerprint, is not a distinct physical type of print. It refers to how the print is captured or stored, not to the print’s actual physical form. So the option that isn’t one of the three recognized print types is digital.
