Correct answer: A — Multiple teeth on the working side (canine and premolars) share lateral excursive contacts, distributing forces across several teeth

Group function (unilateral balanced) occlusion is a lateral excursive scheme where multiple teeth on the working side (typically canine, premolars, and sometimes the mesiobuccal cusp of the first molar) share simultaneous contact, distributing lateral forces across several teeth. This is an acceptable alternative to canine guidance, particularly when the canine has been compromised (restored, periodontally involved, or missing). Non-working side contacts should still be absent in group function.
