Correct Answer: (a)
Solution:The Rhine is a major river in Europe, flowing through several countries including Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands. However, Berlin is not located on the Rhine River. Berlin is the capital and largest city of Germany, but it is situated in the north eastern part of the country, far away from the Rhine River. Instead, Berlin is situated on the River Spree, which is a smaller river that flows through the city.
