I learned something new today. I've always used the "=" or "AS" when doing column aliases. So when I looked through the choices on this question, "select Id, name name from Person" seemed like the obvious answer, but fortunately I still looked at the remaining choices, and the last one, while easy to overlook if you skimmed the questions would not work as the column source is always on the right side of the equals.
I've been so used to using the AS or "=" I never thought you could omit them. :-)
