The correct answer is D) inner race. When removing roller bearings from a shaft, the force of the puller should be applied to the inner race of the bearing. This is because the inner race is the component of the bearing that is directly mounted on the shaft. Applying the force to the inner race allows the bearing to be safely and effectively removed from the shaft without damaging the other bearing components, such as the outer race, retainer plate, or rolling elements. The other answer choices are incorrect because applying force to the outer race, retainer plate, or raceway could potentially damage those components and make the bearing unusable after removal.
