The circumferential clasp when used with tooth supported partial dentures:: (A) Is usually the most logical clasp to use, (B) Has good retentive and stabilizing ability, (C) Both, (D) None
Answer is C. The circumferential clasp is usually the most logical clasp to use with all tooth-supported partial dentures, because of its retentive and stabilizing ability. 
Only when the retentive undercut may be approached better with a bar clasp arm or when esthetics will be enhanced, should the latter be used.
