关于prep08 222的小问题 谢谢解答啊！！

莽莽要上7

同志们有个问题想请教一下~~Although people in France consume fatty foods at a rate comparable to the United States, their death rates from heart disease are far lower in France.
A. people in France consume fatty foods at a rate comparable to the United States, their
B. people in France and the United States consume fatty foods at about the same rate, the
C. fatty foods are consumed by people in France at a comparable rate to the United States's, their
D. the rate of fatty foods consumed in France and the United States is about the same, the
E. the rate of people consuming fatty foods is about the same in France and the United States, the

排除选B没有问题，但是有个地方我有疑惑，就是prep解释中CD说comsumed in France and the US错误，应该在US前面加上prep. in
平行介词最好不要省略
但是问题来了~正确的B选项中US的前面也没有in的啊
这个是为什么？

多谢多谢！！
