well, any of them could be correct, depending on the context (= both the grammatical context and the intended meaning of the sentence).
more generally, if you think that this sort of question will have an answer -- in the complete absence of any context -- then it's likely that you don't understand the structure of the english language well enough to take this exam yet.
you may want to step away from the gmat for a while, and just
familiarize yourself with the english language. just read, read, and read some more, and pay close attention to how things are phrased and written.
