Looks like this should have been a poll.
Lots of good stuff here. From my limited experience, I'll chime in with benallen on the "need good D behind him" if your pitcher's a guy who pitches to the bats. It took me a while to figure that out, and with a good D, my low stuff guys improved markedly.
Personally, I'd go with either pitcher B or C. Probably C.
For me, I'm always looking primarily at a guy's WHIP, so the fewer the baserunners, the better. That means control from my perspective, with the other elements falling secondary.
