AI Explanation
The correct answer is D) high temperatures to develop as a result of churning. Packing extremely soft grease into a roller bearing will cause high temperatures to develop as a result of the churning action. This is because the soft, excessive grease will get churned and agitated within the bearing, leading to increased friction and heat generation. The other answer choices are incorrect because they do not accurately describe the primary issue caused by packing too much soft grease into a roller bearing.
