Which natural resource is mort important to the economy of western europe today

a coal

b gold

c iron ore

d oil

Iron ore is the most important thing your looking for.

I believe oil is not it of the fact that most of it is either in the western hemisphere (Bolivia) or in the Middle East. The main natural resource that is most important is iron ore, due to the fact that there are vast deposits of it in Germany, Belgium, Netherlands, etc.
