A. Quotation marks

A. enclose it in quotation marks.

Because using quotation marks around a word indicates that it is being used in a nonstandard or informal way. Just remember to use those quotation marks wisely, or else you might end up "misunderstood" or "looking like you're trying too hard."

To indicate that a word is slang or informal usage, you can enclose it in quotation marks. This helps to distinguish it from formal language and shows that it is being used in a non-standard or colloquial manner. For example, if you were writing a sentence and wanted to indicate that the word "gonna" is a slang term for "going to," you would write: "I'm gonna meet her later."

So, the correct answer is A. Enclose it in quotation marks.

Yes, D.
