The statement is true because fingerprints are indeed classified into three main categories: arch, loop, and whorl. Each of these classifications reflects distinct patterns formed by the ridges on the surface of fingers.

Arches are characterized by ridges that enter on one side of the finger, rise in the center, and exit on the opposite side, creating a wave-like pattern. Loops contain ridges that enter from one side, curve around, and exit the same side, with a central core that can differ based on the specific type of loop. Whorls are identified by circular or spiral ridge patterns where the ridges make at least one complete turn around the core.

Understanding these classifications is crucial for law enforcement professionals involved in fingerprint analysis and identification as they help in both the processing of fingerprints and the categorization needed for forensic comparisons. The assertion that fingerprints fall into only two categories or four categories would be inaccurate, as the established system recognized by forensic experts consists of those three distinct main types.
