What fluid levels should be checked during a vehicle inspection?

During a vehicle inspection, it's important to check multiple fluid levels to ensure the vehicle operates safely and efficiently. Engine oil is crucial for lubricating the engine components, while brake fluid is vital for the braking system's proper functioning. The coolant reservoir needs to be checked to maintain the engine's temperature and prevent overheating, and other fluids such as transmission fluid and power steering fluid should also be monitored as they are essential for the vehicle's overall operation.

Checking only a limited selection of fluids, such as just engine oil and brake fluid, does not provide a complete picture of the vehicle's condition. Likewise, ignoring essential fluids like coolant can lead to serious engine damage or failure. Thus, option B encompasses a comprehensive inspection of crucial fluid levels that contribute to the vehicle's performance and safety.
