The correct answer is to click on help.

Explanation: When you are unable to find a command that you need, the best option is to select help. Once in the help menu, you can search for any commands that you need. Help is normally found in Microsoft programs by pressing F1.

In this case, Mateo could have accessed the undo command by pressing control+Z.
