Correct answer: BNo teeth should contact on the non-working side

In canine-guided (canine-protected) occlusion, during a lateral excursion the canines on the working side contact and immediately disocclude all other teeth — including all teeth on the non-working (balancing) side. Non-working side contacts are considered potentially destructive as they create lateral forces on posterior teeth without the proprioceptive protection of the canine. Elimination of non-working side interferences is a key goal of occlusal adjustment.
