I think I would go-around (a) at most airfields because I don't think option (c) can ever be a sensible course of action even if you can get away with it. But holding off (b) at a big airfield where the ATC are clearly swamped by RT and you have plenty of runway to land on is a reasonable option IMHO (especially when that's what the instructor acting as PIC in the other seat is telling you to do).
