As a student at UNA (but not a member of any of our four Panhellenic organizations), I'm pretty sure I can guess who A was - and I can give you my honest opinion that if D is also who I think it is based on other comments (if it is indeed the struggling chapter), I'm actually not surprised that this happened.
If I know who A is (my guess is pretty much based on what you reported their pref night thing being and me connecting symbols that are public knowledge with that), then recruitment for that particular group is always extremely competitive. I would almost go so far as to say that the group might be considered by quite a few here on campus to be the top group, due to their reputation, involvement, and record as far as things like spirit competitions and that sort of thing goes.
I would actually advise her, if she really wants to be a part of A, to perhaps go through recruitment here again next year, and keep getting to know girls in each group for the rest of this year. But I recommend doing it again because typically there are a few quota spots reserved specifically for non-freshmen (of course, I'm assuming your sister IS a freshman, which she may well not be), and it might actually work out in her favor.
If you feel like discussing anything more, but you don't feel comfortable doing it directly on the forum, you can feel free to PM me. I know plenty of girls in each of our four groups, even went to high school with some and are involved in different things on campus with them, so I've got a pretty good view of things for a Panhellenic GDI.
