The ability of a file to be opened with other applications or older versions of the application is called what?

• A. Compatibility
• B. Compression
• C. Backstage View
• D. Excel Table

Answer: (A)

Compatibility is the ability of a file to be opened by different applications or by older versions of the same application. It means saving or exporting in a format that other programs can read, so people who don’t have the latest software can still access the content. For example, saving a document in a widely supported format like an older Word format or exporting to PDF helps ensure compatibility across programs and versions. The other options aren’t about cross‑application openness: compression reduces file size, Backstage View is a file-management area in the app, and an Excel table is a way to organize data within Excel.
