Which of the following actions will help you correct a spelling error immediately?

Selecting the option to right-click on the marked word and choose a suggestion is an effective way to correct a spelling error immediately. When a misspelled word is highlighted or underlined, right-clicking allows you to access a context menu that presents corrections based on the software's built-in dictionary. This feature streamlines the editing process by providing quick, appropriate suggestions that can be applied with a single click, making it a practical choice for maintaining accuracy in your writing.

Other methods, such as deleting the entire word or using the undo function, generally do not directly address the spelling error in a timely manner. Deleting the word requires the additional step of retyping it, which may not ensure the correct spelling. Utilizing Ctrl + Z to undo is more suited for reversing recent changes but does not specifically target spelling corrections, thus making it less effective for addressing the immediate issue of a spelling mistake.
