A shipping paper says "UN1203, Gasoline, 3, PG II" but the package labels show Class 8 corrosive. What is the best driver action?

1. Stop acceptance and have the shipper resolve the inconsistent hazard communication
2. Use a corrosive placard because labels always override papers
3. Use a flammable placard because papers always override labels
4. Carry both placards and ignore the discrepancy
