Which two European regions have the most similar physical geography?

a. Great Britain and Iceland

b. Scandinavia and the Northern European Plain

c. The Iberian Peninsula and Great Britain

d. The Northern European Plain and the Central Russian Upland

I believe the answer is: The Northern European Plain and the Central Russian Upland

Both of these regions had a particularly low elevation, located near water source, and consist of soils that had good amount of Grass.

Because of this, these territories are a very good place to established commercial farming.
