The question asks which menu in Excel is used to remove duplicate values. Microsoft Excel organizes its functionalities into various tabs on the Ribbon interface, each grouping related commands for specific tasks.
The correct answer is A: Data. The 'Data' tab on the Excel Ribbon is specifically dedicated to tools for managing, analyzing, and manipulating data within a worksheet. This tab contains commands for sorting, filtering, data validation, text to columns, and importantly, the 'Remove Duplicates' feature. This tool allows users to quickly identify and eliminate redundant entries from a selected range or table, which is essential for data cleaning and ensuring data integrity.
- B: Tools is incorrect. While older versions of Excel might have had a 'Tools' menu, modern Excel uses the Ribbon interface, and 'Tools' is not a standard tab for this function.
- C: Formatting is incorrect. The 'Formatting' commands (found primarily on the 'Home' tab) deal with the appearance of cells and data, such as fonts, colors, and borders, not with the structural manipulation or removal of data entries.
- D: Layout is incorrect. The 'Page Layout' tab is primarily concerned with page setup options for printing, including margins, orientation, and themes, not with data cleaning or manipulation.
Thus, for tasks involving data management like removing duplicates, the 'Data' tab is the appropriate menu.
