______ function in MS-Excel 2010 enables a user to save the changes that have been made in the primary file in a new file.

Correct option is A

Correct Answer: A) Save As
Explanation:
· The Save As function allows a user to create a copy of the currently open file with a different name, file format, or in a different storage location.
· By using "Save As," the original (primary) file remains unchanged in its last saved state, while all recent changes are recorded in the newly created file.
· This is a fundamental tool for version control or for using an existing document as a template for a new one.
Information Booster:
· In MS-Excel 2010, the "Save As" command is located within the Backstage View, which is accessed by clicking the File tab.
· The keyboard shortcut for "Save As" is F12, which immediately opens the dialog box to specify the name and location for the new file.
Additional Knowledge:
· Save: This function updates the current primary file with any new changes. Unlike "Save As," it does not create a new file; it simply overwrites the existing version of the document.
· Open: This command is used to access and load an existing file that has already been saved on the computer or a network drive into the Excel application.
· New: This function is used to create a completely blank workbook or to start a new file based on an available pre-designed template.
