Answer» Correct Answer - Option 2 : Fingerprints The correct answer is Fingerprints. A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. The three types of fingerprints are Whirls, loops, and ridges. The retina of the eye is also used with the fingerprint as it is found that fingerprints are not 100% unique. The Arch is the rarest type of fingerprint.
