A Data Analyst has the following dataset.

Common Characters is appropriate because the five values contain essentially the same characters but differ in capitalization, punctuation, separators, and—in one case—the order of the first and last names. Tableau Prep’s Common Characters fuzzy-matching algorithm removes punctuation, duplicates, and whitespace before evaluating the character fingerprint. Tableau specifically documents that values such as “John Smith” and “Smith, John” can be matched by this technique because their characters are equivalent despite being reordered. Pronunciation is intended for values that sound alike, while Spelling uses edit-distance similarity and is better suited to typographical variations. Manual Selection would require the analyst to choose the values explicitly instead of grouping them automatically. Therefore, B is the verified answer.
