When I edited an earlier question I wasn't sure whether to completely change the "A" form into the "B" form:
A. How do the below three sentences differ in their meaning and which one has the answer 'yes'?
B. How do the below three sentences differ in their meaning and which one is affirmatively answerable?
Since I suppose both are grammatical, I wonder which one, "A" or "B", sounds more natural English? If none of the above sounds natural, what is the reason?
