Which action is commonly accessed via the File tab?

• A. Insert a chart
• B. Start a spell check
• C. Apply a design theme
• D. Open a document

Answer: (D)

The File tab is where you handle file management for your document. It’s the place you go to open, save, print, or share files—essentially actions that deal with the document as a file rather than its content or formatting. Opening a document fits there because you’re loading an existing file into the workspace to begin or continue work.

The other actions sit elsewhere in the interface: inserting a chart is a feature of content creation found under the Insert tab; starting a spell check is part of proofreading tools found under Review or Editor; applying a design theme is a formatting/appearance option found under the Design tab. So opening a document is the action most logically associated with the File tab.
