I don't know how things are in the US, but here you can rent "cheap" rooms to stay during the whole semester. We call it a "kot", but those other Dutch people call it a "studentenkamer".
I live only 40 minutes away from my university by train and I stay at a "kot". But that's mostly because I hate Belgian trains. They're a living nightmare.
So, I'd chose for option A, but then again, things are totally different in the USA then in my country, so I don't know how much it will cost you.
