Show answer and explanation
B black-red-gold schwarz-rot-gold
Why?
The state flag of Lower Saxony uses the German colours black-red-gold, with the state coat of arms (the white horse on red) in the middle. So the colours are black-red-gold, not white-blue (Bavaria) or black-yellow (Baden-Württemberg).
Erklärung auf Deutsch
Die Landesflagge von Niedersachsen ist schwarz-rot-gold mit dem Landeswappen (weißes Pferd auf Rot) in der Mitte.
Remember: Lower Saxony: German colours plus white horse.
