Explanation
A data dictionary documents the system catalog by defining all data elements within a database - including field names, data types, relationships, constraints, and meanings - making it the authoritative reference for understanding the database's structure and content. A standard operating procedure (A) describes step-by-step processes for tasks, not data structure. System requirements documentation (B) captures what a system must do functionally, not how its data is organized. A project plan (C) tracks timelines and milestones for project execution, which is entirely unrelated to documenting data.
Memory tip: Think of a data dictionary like an actual dictionary - just as a dictionary defines words, a data dictionary defines your data fields and their rules.
