Comments can be added to cells using A. Edit > Comments B. Insert > Comments C. File > Comments D. View > Comments

The correct answer is: B. Insert > Comments

To add a comment to a cell in Excel, follow these steps:

1. Select the cell that you want to add a comment to.
2. Click the Insert tab.
3. In the Comments group, click the New Comment button.
4. A comment box will appear next to the selected cell.
5. Type your comment in the comment box.
6. To close the comment box, click anywhere outside of the box.

The other options are incorrect because:

• A. Edit > Comments will open the Comments pane, which displays all of the comments in the active worksheet.
• C. File > Comments will open the Comments dialog box, which allows you to manage comments in the active workbook.
• D. View > Comments will toggle the display of comments in the active worksheet.
