B black-red-gold schwarz-rot-gold
Why?
The state flag of Rhineland-Palatinate is black-red-gold, the German national colours, with the state coat of arms in the upper corner near the flagpole. White-red is Hamburg's flag and green-white-red is North Rhine-Westphalia's. Several states use black-red-gold with their own coat of arms.
