• D. Five

Answer: (B)

Fingerprints are categorized primarily into three main types: arches, loops, and whorls. Arches are characterized by ridges that enter from one side and exit on the other without looping back. Loops have ridges that enter from one side, loop around, and exit on the same side. Whorls consist of ridge patterns that form circular or spiral shapes. This classification system is foundational in forensic science and criminal investigations, as it helps in accurately identifying individuals based on their unique fingerprint patterns. Understanding the three main types of fingerprints is crucial for law enforcement officers, as it plays a significant role in evidence collection and analysis.
