The correct answer is Files and objects in an object storage bucket.

Files and objects in an object storage bucket are stored as binary blobs without a fixed schema and they commonly include images videos audio logs backups and arbitrary files which makes them unstructured when kept in object storage.

Relational database table represents structured data with fixed schemas columns and typed fields so it is not considered unstructured.

JSON documents are typically considered semi structured because they use keys and nested structures that can be parsed and queried and they differ from unstructured binary objects.

NoSQL table entities are stored with defined keys and attributes in database services and they are considered structured or semi structured rather than unstructured.
