Hi,

Since C is true, then A is indeed quite likely to be true, but not necessarily. We know that generally, more examined means better chances of winning. Sure there can be exceptions, but the odds are in favor of the program that examines more moves. This shows that A is very likely to be true, however, it does not have to be true. Perhaps if the two programs are played on the same computer. (Which is true of A but not of the passage) then this is one of those possible exceptions.
