Which statement about fingerprint pattern groups is accurate?

• A. Loops, Whorls, Arches are the three main pattern groups.
• B. Oval is one of the three main groups.
• C. Arch is not a recognized pattern group.
• D. Whorls are not included in main patterns.

Answer: (A)

The key idea is how fingerprint patterns are grouped. The standard primary pattern groups are loops, whorls, and arches. This classification is what forensic practitioners use to organize and compare prints, with each group defined by characteristic ridge patterns: loops enter and exit on the same side, whorls form circular or spiral patterns with at least two deltas, and arches rise from one side to the other with ridges that don’t create a delta. Oval isn’t considered a main group in this traditional framework, though some prints may be described using more specific or irregular terms. Arch is indeed a recognized main group, and whorls are included as one of the three.
