punctuation - How to punctuate a quoted question within a question?

How would I punctuate the bold portion?

"Who are you?" she asked.

"Wait," I replied, "did you just ask me Who are you?"

I would use the following:

"Wait," I replied, "did you just ask me, 'Who are you'?"

• Comma before the quote




• Quoted with single quotation marks (instead of italics, which I'd consider another option)




• Closing quotation mark before the question mark




• Only one question mark (for my question, not the quoted one)

Is this correct?

Answer

Here's the correct version:

"Wait," I replied, "did you just ask me, 'Who are you?' "

Some things to notice:
1. The statement being quoted is a question, so you need the question mark in the embedded quotation marks. You don't need a second question mark. A sentence can have only one end punctuation mark.
2. The comma before the embedded quotation, which follows standard format for introducing a quotation.
3. The space between the single and double quotation marks at the end.

If I were to revise this, I would write this:
"Wait," I said. "Did you just ask me who I am?"
