Answer: O Use Hidden text.
Step-by-step explanation:
The easiest option for Ryan to print the document without the answers would be to use Hidden text. This is a feature in Word that allows you to hide text in a document without actually deleting it. Ryan can simply select the text he wants to hide (the answers) and then go to the Home tab, and in the Font group, click the Hidden button. This will make the text invisible but still present in the document. Ryan can then print the document, and the answers will not be visible.
Using hidden text allows Ryan to quickly and easily hide the answers and still have access to them in case he needs to make any changes or corrections.
Deleting the answers would mean that Ryan will lose the answers and will have to re-type them.
Including the answers on an additional sheet would mean that Ryan would need to prepare two different sheets.
Changing the font color for the answers is not a secure way to hide the answers, as someone can easily change the font color back to the original color.
