Which type of fingerprint impression is commonly found on smooth, non-porous surfaces such as glass, metal, or plastic?
A. Latent fingerprint B. Plastic fingerprint C. Visible fingerprint D. Rolled fingerprint
Explanation: Latent fingerprints are usually not immediately visible and require additional techniques for development on smooth, non-porous surfaces. These surfaces do not absorb sweat and oil from the ridges of the finger, resulting in latent fingerprints that are commonly found on such surfaces.
