Correct Answer:
B. Save as
To create a copy of an existing document while keeping the original intact, the "Save as" function is used. This command allows the user to save the current document with a new name, in a different location, or in a different file format, effectively creating a duplicate. Therefore, the correct option is B: Save as.
- A: Save overwrites the existing document with the current changes.
- C: Print creates a hard copy of the document.
- D: Export typically converts the document into a different file format, which might create a copy but is not its primary purpose for simple duplication.
