The question pertains to the functionality of common keyboard shortcuts in spreadsheet applications, particularly those used for copying and pasting data between worksheets.

When a user selects a range of cells in a spreadsheet and presses Ctrl + C, the data in those cells is copied to the clipboard. This allows the information to be duplicated without altering or removing the original data.

Following this, if the user navigates to a different worksheet (even in a different spreadsheet file) and presses Ctrl + V, the data from the clipboard is pasted into the new location. This operation leads to the data being replicated in the new worksheet.

Let's examine why each of the given options is correct or incorrect:

• The selected cells are deleted from the original worksheet. - This is incorrect. The paste operation using Ctrl + V only duplicates the data; it doesn't delete the original data from the original worksheet.
• The selected cells are saved to a new file. - This is incorrect. The operation simply involves copying and pasting data within worksheets, not saving data to a new file.
• The selected cells are moved to the new worksheet. - This is incorrect. The cells are not moved. 'Moving' would imply they are removed from the original location, which does not happen with Ctrl + C and Ctrl + V.
• The selected cells are copied to the new worksheet. - This is correct. Using Ctrl + C copies the data, and Ctrl + V pastes it, replicating the data in the new worksheet without removing it from its original location.

In conclusion, the data is copied to the new worksheet, preserving its integrity and original state in the first worksheet.
