What year did the first scientific method of classifying fingerprints appear?

• A. 1858
• B. 1877
• C. 1892
• D. 1880

Answer: (D)

The main idea being tested is when a systematic way to categorize fingerprint patterns first emerged, marking fingerprints as a reliable method for identification. Henry Faulds around 1880 argued that fingerprints are unique and permanent and proposed organizing them into categories to aid identification, which is the initial move toward a formal method of classification. This moment is seen as the birth of a structured approach to grouping ridge patterns, even though later work would refine and formalize the system. Later, Francis Galton’s 1892 publication and classification scheme standardized the categories (loops, whorls, arches) and solidified the practical method used for forensic identification. So, the year 1880 is recognized here as the beginning of the scientific approach to classifying fingerprints.
