I'd say that your answer is D) <span>A region with a strong unified sense of culture</span>
Both options A) and B) are used to identify sedimentary rock.
The conditions the rock was formed under & the composition of the rock itself are used to identify sedimentary rock.
B) when it was formed, does not make [identifying] a rock sufficient. Same goes for C) where it was formed, this may help with the identification of a different rock (i.e.,igneous rock), but not sedimentary. As sediments basically make up this type of rock.
