Seneca has just applied conditional formatting and realizes that she has made a mistake. Which action should she take to fix the mistake?

The quickest way to reverse a conditional formatting change made by mistake is to use Undo or press Ctrl+Z. This reverses the most recent action without requiring Seneca to find and remove rules manually. The other choices involve deleting or clearing rules rather than simply undoing the last action.
