Best option: B. Simon classification  

Reasoning (concise):  
Simon’s system analyzes malocclusion in three spatial planes and, in the sagittal (depth) direction, it employs the “canine law,” which uses the position of the maxillary canine cusp relative to the orbital plane to judge antero-posterior discrepancies. None of the other listed classifications (Bonnet, Dewey, Lischer) invoke the canine law in their sagittal assessment. [Ricketts, 1975, PMID 1059336]
