Choice A: We conducted a survey of those in the immediate area and asked which type of notary stamp each liked best.
Essentially, the only thing that differentiates Choice A from the rest, is it's pronoun used.
In the original, the pronoun phrase used in relation to the adjective "those," was "he or she."
From this we can infer that Choice B is out of the question since it only states "she."
Choice C, though a tempting choice, is incorrect since the word "they" isn't inclusive enough.
Choice D is erroneous because it does not provide more clarity than the original. In fact, it doesn't even seem like a revision since the two pronouns were joined by a forward slash.
