It depends. All will be fine. Fatter tires can run with lower pressure, which gives a smoother ride and more 'floatation' over soft surfaces. Narrower tires tend to be lighter and roll a little faster but must be run at higher pressures to keep from pinch-flatting.

You must consider your weight and how rough the surfaces are. But even then, all will be fine. I personally use 700 X 322C tires on my 14 km rough paved and dirt road commute and I weigh 270 lbs (me + bike + gear = over 300 lbs, I am sure) and I have no problems and my bike rolls nice and fast.

If you are riding primarily on pavement then the narrower ones might be a bit faster (but not by much) if they are the same tire other wise. But any one of them will be fine.
