Hmm, I'm not totally sure about this one. Metropolitan, cosmopolitan, and urbane all seem like they could describe a hotel in a city center. I'll have to think this through carefully.

I'm feeling pretty confident about this one. The key is ensuring the data can't be tampered with, so I'm going with B. Data integrity control.
