What should a driver do if an unverified pedestrian on the street claims that they are the passenger who placed the app order?

1. Immediately open the door and drive away without checking anything
2. Politely verify the passenger's registered platform nickname, destination, or the last four digits of the order mobile number before allowing entry
3. Demand that the person pay RMB 100 in cash before speaking
4. Call the municipal fire brigade to inspect their clothing
