Correct answer: D — Stress control on terminal abutments

Kennedy Class I distal-extension dentures are tissue-and-tooth supported, so stress control on terminal abutments is central to design. Rigid clasping without appropriate rests and indirect retention can increase torque on abutments. The teaching point is that support, retention, indirect retention, and impression strategy must address differential tissue displacement.
