I like the looks of A--the spokes appear to be slightly curvilinear (not sure if I have used that word in written form since the 80s or earlier) which is more consistent with design of the Soul--B seems to be a bit too linear/mainstream. That being said either would be fine (but "a" would be finer though).
I really like the Fathom blue color--none available on our area when we needed to purchase the Soul.
It really doesn't matter, because, with such low-profile tires, hit a big pot hole and either rim will be destroyed. So if there's a price difference, pick the cheapest one, and buy one extra for a spare, because you'll likely need it.
