Answer:
a. Technician A only
Step-by-step explanation:
The best way to ensure that the replacement wheel work and do not show any fault is that the load capacity, displacement, width, diameter and mounting configuration are the same, because in case the width or diameter varies, the wheel could be improperly installed, if the mounting configuration or the load capacity are different it could cause safety problems, and in case the displacement is different it could generate variations in the vehicle's performance as reduction of the fuek efficiency
On the other hand, technician B only indicates that the same total width should be had as the original tires, but doesn't take into account that if the tire height is changed would affect the speed measurement system, in addition to the rest of the problems that can be caused by just taking into account one of the characteristics of the system.
