求助prep grammar

1)A new hair-growth drug is being sold for three times the price, per milligram, as the drug's maker charges for another product with the same active ingredient. A, as, B. than, C, that, D, of what, E, at which

answer:C, mine: B请教three times...that这种结构对么？觉得B也有点问题

2)Over 75 percent of the energy produced in France drives from nuclear power, while in Germany it is just over 33 percent.

C whereas nuclear power accounts for just over 33 percent of the energy produced in Germany

D whereas just over 33 percent of the energy comes from nuclear power in Germany

E compared with the energy from nuclear power in Germany, where it is just over 33 percent

answer:C, mine, E的it指代有问题，为什么选C比D好？对称来讲还是D比较好呀？

Thanks

帮自己顶一下，大家帮忙看看哦：）谢谢啦

1. that引导的定义从句是修饰price的, 不是3 times that

2. D中in Germany可以是power的定语也可以是comes from的状语,造成歧义.C避免了这个问题.

啊。。原来被逗号隔开拉，发现了：）

谢谢啦
