A meso compound will always have a (R,S) or (S,R) configuration because its highest priority groups are always on the same side of a specific plane.

A meso compound will always have an (R,S) or (S,R) configuration because it has identical substituents attached at every chiral center.

A meso compound will always have an (R,S) or (S,R) configuration because it has two achiral centers.

A meso compound will always have an (R,S) or (S,R) configuration because its chiral centers are adjacent to each other.
