Which field indicates whether a document has images?

• A. a numeric field counting images
• B. a single choice field indicating whether a document has images
• C. a text field with image URLs
• D. a boolean only for production documents

Answer: (B)

The field being tested is the most direct way to express whether images exist on a document: a simple presence flag that stores a yes/no value. Using a single choice field to indicate whether a document has images gives a clear, unambiguous signal that’s easy to query, filter, and validate. It avoids the extra steps of counting how many images there are or parsing URLs, and it remains stable even if images are added or removed. Counting images with a numeric field can tell you how many there are, but it isn’t as immediate for checking presence and requires extra rules to interpret the count (for example, you must check if the count is greater than zero). A text field with image URLs stores the actual image links but doesn’t provide a clean, binary indication of presence, making presence checks less efficient and more error-prone. A boolean only for production documents ties the presence signal to production status, which isn’t appropriate for determining whether a document has images in general.
