Only the fuel system
Electrical system, fuel system, and overall maintenance
Only the tires
Only the engine

The correct answer is: Electrical system, fuel system, and overall maintenance

When discussing vehicle fire safety, it's crucial to take into account multiple systems that could pose a risk of fire. The electrical system can be a source of ignition if there are shorts or faulty wiring, while the fuel system is pertinent because leaks can lead to flammable vapors that ignite easily. Additionally, overall maintenance plays an essential role in fire prevention; components like the engine, tires, and brakes can also contribute to hazardous conditions if not properly maintained. Choosing to focus on just one aspect, such as the tires or the engine alone, ignores the interconnected nature of these systems and their potential fire hazards. A comprehensive approach ensures that all potential fire sources are addressed, enhancing the overall safety of the vehicle. Thus, maintaining focus on the electrical system, fuel system, and ensuring thorough overall maintenance is vital for minimizing fire risk in vehicles.
