Arriva is owned by the Deutsche Bahn.

The answer is True because Arriva is indeed owned by the Deutsche Bahn. Arriva is a multinational public transport company based in the United Kingdom, which operates bus, train, tram, and waterbus services in 14 countries across Europe. In 2010, Deutsche Bahn acquired Arriva for approximately £1.59 billion, making it a subsidiary of the German state-owned railway company. This acquisition allowed Deutsche Bahn to expand its presence and offer its services in various countries through Arriva's extensive network.
