229. Which country is a neighboring country of Germany?

Answer options

1. Spain
2. Bulgaria
3. Norway
4. Luxembourg

Explanation

Germany currently borders nine states: Denmark, Poland, the Czech Republic, Austria, Switzerland, France, Luxembourg, Belgium, and the Netherlands. The legal consolidation of these borders rests on key treaties such as the 1970 Warsaw Treaty, the 1973 Treaty of Prague, the 1990 Two‑Plus‑Four Treaty, and the 1990 German‑Polish Border Treaty. Border and customs matters lie within the Federation’s exclusive legislative competence (Article 73 of the Basic Law), while European integration and Schengen free movement are constitutionally anchored in Article 23. Luxembourg is a western neighbor along the Moselle, Sauer, and Our rivers; the 1985 Schengen Agreement was signed in Luxembourg and continues to shape cross‑border mobility.
