Which statement about Binary resources is true?

• A. They are used to reference other resources.
• B. They are non-persisted resources.
• C. They can contain any content, such as text, image, pdf, zip archive.
• D. They are used to model patient data.

Answer: (C)

Binary resources serve as a universal container for raw binary data in FHIR. They are not about modeling patient data themselves; rather, they store the actual bytes of a file or document and indicate what type of content they hold via a MIME type. Because the storage is generic, the data can be any binary content—text, images, PDFs, ZIP archives, and so on. This makes the Binary resource the appropriate place to keep unstructured or large binary payloads that other resources may reference or link to, using attachments or URLs.
