During unloading, a student drops a paper just in front of the bus and starts to bend down. What is the best driver response?

1. Stop the student with a clear command and keep the bus secured until the child is safely away or the item is retrieved under the driver's control
2. Wave the student to grab it quickly before traffic moves
3. Cancel the warning lights so traffic can proceed
4. Move the bus forward slightly so the paper is easier to reach
