It should be C.United States...Hope this helps
I think it might be either
A. Low plain rising to towering mountains
Or
D. Series of parallel high mountains
Because the Atlas Mountains are located there but I’m not really sure which one it is sorry.
Industrializing place would have offered much pollution and settling, so the conditions wouldnt have been healthy for nature. Therefore, there would be a decrease in life and biodiversity, less trees, plants, and animals living there, etc.
