What is the official language of Switzerland?

Switzerland is known for its linguistic diversity, officially recognizing four national languages: German, French, Italian, and Romansh. The presence of multiple official languages reflects the country's multicultural population and regional identity.

German is predominantly spoken in the central and northern regions, while French is mainly used in the west, known as the Romandy region. Italian is primarily spoken in the southern region, particularly in the canton of Ticino. Romansh, though less widely spoken, is recognized as an official language and is used mainly in some areas of Grisons (Graubünden) in southeastern Switzerland.

By acknowledging all four languages as official, Switzerland promotes equality among its different cultural groups and helps preserve its rich linguistic heritage. This inclusive policy not only fosters unity within the country but also accommodates the needs of its diverse population, making option D the most accurate choice.
