B Correct answer
Explanation

Excel documents traditionally use the .xls file extension (for older versions) or .xlsx (for newer versions). .doc is for Word documents, and .excel is not a valid file extension. File extensions identify which application created the file and which should open it.

AI explanation

The traditional file extension for Microsoft Excel workbooks (used in Excel 97–2003 binary format) is '.xls'. This is a widely known, standard fact of computer literacy (later versions use '.xlsx' for the XML-based format, but '.xls' is the classic and still-recognized Excel extension). '.excel' is not a real file extension — file extensions in Windows/DOS naming conventions are short abbreviations, not the full application name. '.doc' is the Microsoft Word document extension, not Excel's. 'None of these' is wrong since .xls is a valid, correct answer among the choices.
