Who is responsible for keeping a school bus clean?

Answer: B — The driver

The school bus driver is responsible for keeping the bus clean. While it is important for students to do their part in keeping the bus clean, such as picking up their trash and avoiding making a mess, the ultimate responsibility falls on the driver. The school administration may have certain rules or expectations for cleanliness, but it is ultimately up to the driver to enforce and maintain them. The cleaning staff may also play a role in keeping the bus clean, but the primary responsibility falls on the driver who spends the most time on the bus and is responsible for its overall maintenance and upkeep.
