What does Level 1 detail in fingerprint analysis include?

• A. Ridge flow: core, deltas, scars, classification, and orientation.
• B. Only ridge flow.
• C. Substrate and matrix.
• D. Deposition pressure.

Answer: (A)

Level 1 detail focuses on the big-picture ridge pattern of a fingerprint. It describes the overall ridge flow and pattern type (loops, whorls, arches), where the core and deltas are located, and the general orientation that supports broad classification. These elements give you the basic layout of the print and allow you to categorize it at a high level. The option that includes ridge flow along with core, deltas, scars, classification, and orientation captures this broad pattern and how it’s organized, making it the best fit for Level 1 detail. Elements like the substrate or how hard the print was pressed affect quality or the surface rather than the pattern itself, and discussing deposition pressure describes conditions rather than the pattern features used for Level 1.
