I narrowed it down to D and E to fulfill the "from x to y" idiom, but the rest seems unclear.


The problem with E seems to be the comma use.
D seems like it shouldn't have a third clause. When something is ranging from X to Y, it seems like you should only have two variables. Ranging from X to Y to Z doesn't sound right.

The OA is D.
