this is one of our (mgmat) questions.
the answer is (b).
here's a reference to another thread in which i posted the correct way to resolve these sorts of things:

the rules i cited in that post do not have exceptions.

this is the problem with people randomly posting questions without answers.
ALWAYS POST THE ANSWER ALONG WITH ANY QUESTION. always always always.
this is absolutely necessary. ideally you should use the "spoiler" function, or put a little space between the question and the answer, but you MUST post the answer given in the source.
i've seen lots and lots of threads, like this one, in which a solid majority of the posters have the wrong answer. we need to counteract this trend by posting answers to all questions.
