A System of Records contains information retrieved by:

• A. An individual's name or other unique identifier.
• B. A department code only.
• C. A random access memory address.
• D. A file size in bytes.

Answer: (A)

A System of Records is a collection of records about identifiable individuals that can be retrieved by using the person’s name or another unique identifier. This means the defining feature is how you access the record—by information that uniquely points to a specific person. Among the given options, only retrieving by an individual’s name or a unique identifier fits this idea, because it directly ties the data to a particular person.

The other options don’t fit this concept: a department code identifies an organizational unit, not a person; a random access memory address is a hardware location, not a way to locate an individual’s record; and a file size is just a measurement, not an identifier used to retrieve a person’s records.
