Final answer:
The correct answer is that only Technician A is right, as visible fuel leaks merit failure of an annual vehicle inspection. A missing fuel tank filler cap would also typically cause a fail, contrary to Technician B's claim.
Step-by-step explanation:
The correct answer is option a) Technician A only. In the context of vehicle inspections, any form of fuel leak is generally considered a safety hazard and would be a legitimate reason for an annual inspection failure. Fuel leaks can pose a significant fire risk and environmental hazard.
Technician B's claim that a missing fuel tank filler cap is not cause for failing an annual inspection is incorrect.
A missing fuel tank filler cap can lead to the evaporation of fuel, can allow moisture or debris to enter the fuel system, and can also cause the check engine light to turn on in many vehicles, all of which are reasons for inspection failure.
Therefore, only Technician A's statement is accurate in this scenario.
Technician A is correct because any visible fuel leak is indeed cause for failure of an annual inspection. Fuel leaks can be a safety hazard and can potentially lead to fires or other accidents. Therefore, it is important to address any visible fuel leaks.
Technician B is also correct because a missing fuel tank filler cap is not cause for failing an annual inspection. While it is important to have a fuel tank filler cap in place to prevent fuel from spilling out or being contaminated, its absence does not directly affect the vehicle's safety.
