Comma after quoted words

[rumik]

This isn't about actual dialogue, but if a word is "quoted" in a list that requires a comma after it. Or a period, or whatever punctuation.
Which of these would be correct?

The author uses words like "x", "y", and "z".
The author uses words like "x," "y," and "z."

I've googled it and found that American English apparently prefers the second style, whereas British English uses the first but with single quotes like 'x', 'y', and 'z'. So I was wondering which one is considered "correct" here

Either will work. Both British and American English are acceptable (consistency is key, though). If an editor mistakenly docks points for the British version, you should ask for a recheck. Be sure to cite your source, though. Happy writing and good luck!

To reiterate... consistency is very important. If you mix the British and American spellings/grammar, you will get docked.

Now, I know. Thank you.
