Which statement describes how a Column ID with both an ID and a name is illustrated?

• A. Includes the ID or name in the Column ID field, as shown by the PublisherName example
• B. Uses only numerical IDs
• C. Is optional and may be omitted
• D. Does not apply to any columns

Answer: (D)

A Column ID that carries both an internal identifier and a human-readable name is typically shown by placing both pieces into the same Column ID field. The PublisherName example demonstrates this approach, where the field displays the underlying ID together with a readable label so the column can be referenced by systems and understood by people. This is the best description because it directly matches how such a Column ID is illustrated—the ID and the name are included in the Column ID field, not omitted or limited to just numbers. Describing it as optional would ignore the need for clear identification, and saying it applies to no columns contradicts common data-model practices where IDs are paired with meaningful names.
