B. There are more living organisms classified as lupus than as Canis.
C. An organism may be classified as Canis but not as Canidae.

A is correct. Remember: Darn King Phillip Came Over For Good Soup. Domain, kingdom, phylum, class, order, family, genus, species. The epithet Canus lupus indicates that the wolf is genus Canus and species lupus.
