There are three main pattern groups for fingerprints. Which is NOT one?

• A. Loops
• B. Whorl
• C. Oval
• D. Arches

Answer: (C)

The main concept here is how fingerprint patterns are categorized into the three primary groups based on the overall flow of the ridges. Loops have ridges that enter from one side, curve, and exit on or near the same side. Whorls form circular or spiral ridge patterns with at least one delta. Arches have ridges that enter from one side and exit the other, rising in the center, with plain and tented arches as subtypes. Oval is not part of this primary three-category framework, so it’s not considered a main fingerprint pattern group.
