Whether C has widespread acceptability depends almost entirely on
information which is not captured in ranked ballots.  At the extremes, C
may enjoy either unanimous popularity, or near total rejection. 
Approval voting is able to distinguish between these extreme cases with
ease.  Ranked methods can only do so to the extent that they encourage
insincere strategy.
