Final answer:
Loops, whorls, and arches are types of fingerprints that are unique to each individual and can be used for identification. Therefore, the correct option is A.
Step-by-step explanation:
Fingerprint classifications include loops, whorls, and arches. Each one stands for a unique pattern found in the skin ridges of an individual's fingertip.
Whorls have spiral or circular patterns, loops have ridges that enter on one side and exit on the same side, and arches have ridges that flow from one side to the other without following a round pattern.
A key idea in forensic science and criminal investigations, this particular configuration of ridges enables the identification and distinction of people based on the distinctive patterns found in their fingerprints.
Therefore, the correct option is A.
