Which of the following is NOT a basic category for alphabetizing names?

The correct answer reflects the fact that nicknames are generally not considered a primary basis for alphabetizing names in formal contexts. When organizing a list of names, the standard approach starts with the last name, then the first name, and may also consider the middle name if applicable. This method ensures a systematic and familiar way to sort names, making it easier for individuals to locate and reference specific entries.

In contrast, nicknames, although sometimes used informally, do not have the same standard structure or consistency and can vary widely among individuals. Their usage in formal lists would likely lead to confusion or inconsistency, as individuals may not always choose to use their nickname in official documentation or identification. Thus, while a nickname might be a personal identifier, it does not fit into the conventional categories used for alphabetizing names.
