A child drops a phone under the front of the bus while boarding. Which response best follows the handbook's safety logic?

1. Keep the child out of the danger zone, secure the bus as needed, and have the driver retrieve or control recovery only when safe
2. Tell the child to crawl under quickly before traffic moves
3. Ask another student to retrieve the phone while the door is open
4. Ignore the phone and move the bus so it can be picked up later
