Concept:A worksheet tab can be renamed by editing its current label directly from the tab itself.
Explanation:In Microsoft Excel, each sheet tab appears at the bottom of the workbook.
To rename a sheet quickly, place the mouse pointer on the desired sheet tab.
Double-click the left mouse button on that tab.
Excel highlights the existing sheet name and enters edit mode.
Type the new name for the sheet.
Press the Enter key on the keyboard to save the new name.
Double-clicking a column or row does not rename the tab.
The Save As command is only used to save a copy of the entire workbook, not to rename a sheet tab.
Answer:C. Double-clicking on the sheet tab; entering the new name.
