Which technician is correct regarding the replacement of damaged springs and adjusting screws?

The choice indicating that Tech A only is correct suggests that Tech A provided accurate information regarding the replacement of damaged springs and adjusting screws. In many automotive suspension systems, replacing springs requires precise knowledge of the system's specifications, including the correct tools to safely remove and install the springs without causing damage to surrounding components. Additionally, adjusting screws must be set to the proper specifications to ensure correct alignment and performance of the suspension system.

It's likely that Tech A's statements addressed these practices, emphasizing safety and precision during the replacement process. This understanding is essential in maintaining vehicle stability, ride quality, and overall performance. If Tech B did not adhere to these critical aspects, or if their information was less accurate, this would clarify why only Tech A's approach is deemed correct.
