There is no "correct one" for your CPU in that list. Typically, newer CPUs add extra instructions that may be more efficient than the corresponding "generic x86" ones. Later CPUs, as long as they also include those instructions, can take advantage of versions optimized for earlier CPUs, but there will also be newer extra instructions that the optimization for the older CPU ignores. In any case, unless you've got some kind of special case, it's unlikely that optimized versions will make any noticeable difference, and may introduce issues regarding software updates.
Go ahead and experiment by trying those various versions and see if you notice any difference.
