Question

what does an outline do?
combines data from different worksheets
copies the headings to the clipboard
performs calculations
groups data by levels

Explanation:

• "Combines data from different worksheets" is not what an outline does (usually for data consolidation tools, not outlines).
• "Copies the headings to the Clipboard" is a copy - paste action, not related to outlines.
• "Performs calculations" is for functions or formulas, not outlines.
• An outline in data organization (e.g., in spreadsheet or document structuring) groups data by levels (like main topics, sub - topics, etc.).

Answer:

D. groups data by levels
