What is the function of the 'Undo' command?

• A. To revert the last action performed in a software application
• B. To save the current document or project
• C. To delete the selected content
• D. To format the text in a document

Answer: (A)

The function of the 'Undo' command is to revert the last action performed in a software application. This command allows users to easily correct mistakes or changes they have made in their work without needing to manually revert each change. For example, if you accidentally delete some text while editing a document or make an unwanted formatting change, using the 'Undo' command will restore the document to its previous state. This makes it a vital tool for enhancing productivity and reducing errors during the editing process.

The other options highlight different functions that do not pertain to the 'Undo' command. Saving a document involves preserving the current state of your work, deleting selected content removes it completely without a direct reversal option, and formatting text applies styles or design changes but does not revert actions. Each of these serves a different purpose in document management and editing.
