Which behavior should a driver discourage to maintain order on the bus?

Permitting students to move around freely can lead to unsafe conditions on a school bus. When students are allowed to roam the aisles, it increases the risk of accidents, as they may lose their balance, block the aisle during an emergency, or distract the driver. Maintaining order on the bus is essential for ensuring the safety of all passengers. By keeping students seated and discouraging unnecessary movement, the driver can minimize distractions, reduce the likelihood of injury, and ensure that the bus remains a safe environment for everyone. The other options, while relevant to maintaining a positive atmosphere, do not inherently compromise safety in the same manner that unrestricted movement does.
