In Excel, which item is the container for all worksheets in a file?

• A. Document
• B. Workbook
• C. Worksheet
• D. Spreadsheet

Answer: (B)

In Excel, the file that contains all the individual worksheets is called a workbook. A workbook is the container for every sheet you add—the separate tabs you see inside the file. Each tab, or page, is a worksheet with its own grid of cells, and you can have many worksheets in one workbook. When you save, you’re saving the entire workbook as a single file (such as .xlsx). A single worksheet is just one page within that workbook, not the container. The term spreadsheet is commonly used to refer to this kind of file, but the specific container that holds all the sheets is the workbook. A document is too generic and not Excel-specific.
