• C. Only listing statutes by number.
• D. A method for organizing court calendars.

Answer: (B)

Legal citation systems in the United States are standardized rules for referencing authorities such as cases, statutes, and regulations. They exist so readers can quickly locate and verify sources cited in legal writing, understand exactly what material is being relied on, and see essential details like jurisdiction, court, year, and pinpoint pages. The Bluebook is the most widely used guide, with other systems like ALWD also common; these rules cover how to format case names, reporter information, volumes, page numbers, and the court and year, as well as how to cite statutes, regulations, and secondary sources. This consistency helps judges, lawyers, and scholars cross-check authorities across briefs and opinions, ensures precision when pointing to specific passages, and facilitates searching in legal databases. For example, a case citation directs you to the exact case in a reporter with the volume and page where it begins, plus the year and court. A statute citation shows the title, code, section, and year. Citations are not random, they’re not limited to listing statutes by number alone, and they’re not about organizing calendars.
