Which of the following command would undo the last operation carried out in Microsoft Word

The command that would undo the last operation carried out in Microsoft Word is "Ctrl + Z". When you perform an action such as typing, deleting, or formatting text in Word, the program keeps track of that action in a history of changes. The "Ctrl + Z" keyboard shortcut allows you to undo the most recent action you performed, effectively reversing its effects. For example, if you accidentally deleted a sentence in your document, you can use "Ctrl + Z" to undo the deletion and restore the sentence. If you want to redo an action that you previously undid, you can use the "Ctrl + Y" keyboard shortcut, which is the opposite of "Ctrl + Z". On the other hand, "Ctrl + W" is used to close the current document or window in Word, while "Ctrl + U" is used to underline text.
