If a professional title is listed after the first and last name of an individual, it becomes:

• A. The third indexing unit
• B. Disregarded

Answer: (A)

In personal-name indexing, the name is divided into indexing units: the first unit is the surname, the second is the given name (or initials), and any trailing designator such as a professional title, honorific, or date is treated as a separate third indexing unit. So when a professional title appears after the first and last name, it is stored as the third indexing unit. This keeps the main heading focused on the surname and given name, while still capturing the title as an additional access point for retrieval.
