Answer: B — It must be in good working order and prevent excessive noise

The requirement regarding the muffler of a motor vehicle is that it must be in good working order and prevent excessive noise. This is essential for several reasons. A properly functioning muffler ensures that the vehicle operates within legal noise limits set by regulations, which helps reduce noise pollution in the environment. Additionally, a well-maintained muffler contributes to the overall performance of the vehicle by ensuring that exhaust gases flow freely, reducing back pressure, and improving engine efficiency. Maintaining proper noise levels not only respects the surrounding community but also aligns with the safety and regulatory standards for motor vehicles. Therefore, keeping the muffler in good working order is crucial for both performance and compliance with the law.
