Final answer:
Technician B is correct; engines can be found in typically 3 different locations. Both Technician A and Technician B are partly correct. Technician A is right about the existence of three general engine locations while Technician B accurately describes two common engine configurations and one less common.
Step-by-step explanation:
Technician B is correct. Engines in vehicles can be found in typically 3 different locations: front engine longitudinal, front engine transverse, and mid-engine transverse.
Both Technician A and Technician B are partly correct. Technician A is right about the existence of three general engine locations while Technician B accurately describes two common engine configurations and one less common.
Technician A states that engines can be found in vehicles in typically 3 different locations. Technician B says the 3 types of engine placements are the front engine longitudinal, front engine transverse, and mid-engine transverse. In this context, both Technician A and B are partly correct. Technician A is correct that there are generally three locations where engines can be mounted: the front, mid, and rear.
However, Technician B has narrowed these down to types based on configuration and location. The common engine placements are indeed front engine longitudinal, where the engine is mounted along the vehicle's length, and front engine transverse, where the engine is mounted across the vehicle's width. Yet, mid-engine transverse is less common, and another engine location, the rear, is also possible. So, both technicians are correct about the different engine locations/types, but Technician B's statement could be more comprehensive. Therefore, the correct answer would be C. Both Technicians A & B.
