Which type of Version changes each time the content in the resource changes?

• A. Business Version
• B. Profile Version
• C. Security Version
• D. Release Version

Answer: (A)

In FHIR, every resource has a version identifier that tracks its history. This version changes each time the resource’s content is updated on the server, giving you a new, distinct version that represents the current business state of that resource. This is why it’s referred to as the business version—the versionId reflects edits to the resource’s data.

The other kinds aren’t tied to every content change: a profile version tracks changes to the constraints or structure defined by a profile, not the resource data itself; a security version would relate to changes in security metadata or access control, which isn’t automatically updated with every data edit; and a release version corresponds to the overall FHIR specification release (like R4, R5), not to individual resource updates.
