On what roads does the recommended speed of 130 km/h apply?

You selected all correct answers. The recommended speed of 130 km/h (Richtgeschwindigkeit) in Germany applies not only on autobahns (motorways) but also on certain rural roadways outside built-up areas. Specifically, it applies on roads outside towns that either have separate carriageways for each direction or have at least two marked lanes for each direction. This recommendation helps ensure safety at higher speeds on roads designed for fast travel and is not a speed limit, but exceeding it can have liability consequences in case of an accident. In summary, whenever you see the characteristics described in answers 1, 2, and 3, the 130 km/h recommended speed applies.
