Answer: (B)

For the air dryer in a school bus, it is essential that it is free from cracks, breaks, or leaks. The air dryer plays a critical role in the air brake system by removing moisture and contaminants from the compressed air before it reaches the braking system. If the air dryer is cracked, broken, or leaking, it can result in improper functioning of the brakes, potentially leading to both performance issues and safety hazards. A functioning air dryer ensures that the air used for brakes is dry and clean, which helps maintain the integrity of the entire braking system. Thus, checking that the air dryer is in good condition during the pre-trip inspection is crucial, ensuring the safety of the bus and its passengers.
