I'm not an expert on this but:
For charged B's I expect naively K+K- as the primary product
of ssbar popping. For neutral B's the primary product should
be e.g. K+K0bar/K-K0.
Of course, K*'s should be also possible. So other combinations
two kaons may also appear.
It becomes more complicated if additional uubar or ddbar are
produced out of the vacuum.
So, in general I would expect that any combination is possible.
