Great question. I think the answer choices were suitably plausible, so it made it hard for me to guess. I happened to guess right. 🙂 Seriously, though, this is good information to know, and the question illustrated it well.

I have only one suggestion. Most other answers include a reference link, and I didn't see one for this question. It's easy enough to look up in Books Online, but if you post future questions, including the link will allow people to click right over to it.

Thanks!
