Correct answer: E — Minor connector with guiding plate

Guiding plates (proximal plates) are components of the minor connector that contact the guiding planes (prepared parallel surfaces) on the abutment teeth. They direct the RPD along the predetermined path of insertion and removal, provide stabilisation against lateral forces, contribute to reciprocation of clasps, and provide some indirect retention. Guiding planes are typically prepared on the proximal surfaces of abutment teeth adjacent to edentulous areas.
