What are the three basic fingerprint ridge patterns, and what term describes small ridge details?

• A. Loops, Whorls, Arches; Minutiae
• B. Arches, Deltas, Ridges; Endings
• C. Loops, Arches, Deltas; Features
• D. Whorls, Deltas, Arches; Cores

Answer: (A)

Fingerprint analysis distinguishes two levels: the broad ridge pattern categories and the tiny ridge details used to compare prints. The three basic ridge patterns are loops, whorls, and arches. These describe how the ridges flow on the print. For the fine-grained details, the standard term is minutiae, which covers features like ridge endings and bifurcations that are used to differentiate one print from another. So the combination of loops, whorls, arches with minutiae is the correct pairing. The other options mix terms that aren’t the standard names for the three pattern types or for the small ridge details (for example, using endings, features, or cores, or including terms like deltas with arches).
