River Danube does not flow through which one of the following capital cities in Europe ?

The River Danube is the second-longest river in Europe, flowing through ten countries and four national capitals. These four capital cities are Vienna (Austria), Bratislava (Slovakia), Budapest (Hungary), and Belgrade (Serbia). While the Danube serves as a vital inland waterway for Eastern and Central Europe, it does not flow through Prague [1]. Prague, the capital of the Czech Republic, is situated on the banks of the Vltava River (Moldau), which is a tributary of the Elbe, not the Danube. Although some travel itineraries may include Prague as a nearby destination during Danube cruises, the river itself does not pass through the city. Therefore, among the given options, Prague is the only capital city not located on the Danube.
