B. All B needs to do is take people with good early game wave clear and good tankiness. As long as they don't feed kills, A will have to double jungle just to try and keep up, and B will need to be very reactionary (if 5 mid, bring 5 of your own, if they have junglers, you can spare one or two for other lanes, etc.) to prevent A from getting early advantages.

A will take quite a few towers, but as long as B holds off the inhibitor they win. And by the time A gets to inhib tower, B will have at least a few levels on them and can clear minions fast enough to hold off the push. From there its just an xp snowball to win for B as A cna't take global objectives without the farm and xp.
