Solution:
Structure III is a Fischer projection of meso-2,3-butanediol.
Structure II is another representation of the same molecule.
Both have opposite configurations at the two stereocentres, i.e., (R,S).
Both possess an internal plane of symmetry.
Therefore, they represent the same meso compound.
Hence, II and III are identical molecules.
