[2025-10-01T19:22:41.853370] [PI reasoning] **Analyzing removable partial denture concept**

I’m looking at the concept of guiding planes on abutment teeth. They create flat surfaces that guide insertion and removal, offer retention through friction, limit lateral forces, and enhance stability. This leads me to conclude that they increase resistance against horizontal movement, making option B the best choice. I should also reference appropriate literature, such as textbooks by Stewart or Krol, and possibly conduct a search for more information on guiding planes and their role in resistance.
