The right answer of course is "each of them can (but only one at a time)" so of the options provided 3 is closest to correct. 1 (the "right" answer) would only be really correct if the question was "how many of them can be rowguidcol columns at the same time".I have to agree to disagree with this statement.
"enabled" is the key word in this question and makes perfect english as the last word in the question. This makes it the main describer for the question.
I don't think the word "enabled" helps at all. The way the question is phrased would allow it to help only if the word "simultaneously" were inserted between "can" and "have" (or after "enabled" if a little sloppiness is permitted).
