Which of these would be least likely to be found in the European plain

These are the options for the question:

A) Russia

B) Germany

C) Rhine River

D) the Pyrenees

And this is the correct option for the question:

D) the Pyrenees

Explanation:

The Pyrenees by definition, are not part of the Northern European Plain because it is a mountain range. The Pryenees forms the natural boundary between the Iberian Peninsula, and the rest of Europe (Europe is also a big peninsula), where the plain is located.

Germany on the contrary, has around a third of its territory in the Northern European Plain, the Upper Rhine River is located entirely within the Northern European Plain, and most of Western Russia is located within the Northern European Plain.
