I would choose E.FightWithGMAT wrote: D. the economy of Britain, France, and Germany, with the unemployment rate that has remained
E. the economies of Britain, France, and Germany, and the unemployment rate has remained
I do not see any big issue with D.
E is changing the meaning here. The sentence presents the 2 ideas that are correlated. E says that both the ideas are separate.
Economy is singular; this is wrong in D?
EITHER: "the economy of B, F, or G..."
OR: "the economies of B, F, and G..."
That mistake must override a change of meaning. To me:
a correct sentence with modified meaning > an incorrect sentence with originally guessed meaning
