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
the answer is C


personally ,i have confusion in the anwer'a", some of the learners say the right anwer is "a', whereas , i am in favor of "c", in that  "it " is ambiguous.

then,i would like to raise some questions :
1.是不是”it“前面有多个名词，一般都是错的，原因是会引起歧义、
2.C和D如果在考场了头脑发昏，肯恩没注意就会选错，那怎么能更好地看清楚呢


thank you for your explanation

About usage of "it":
A). if you couldn't find a noun in singular form, it has no object to refer to, thus wrong.
Derivative of A). if the only singular noun could not be refered because of sentence structure or such grammatical issues, also it has no object to refer to, thus wrong.
B. if more than two singular nouns are in previous context, generally it has to refer to the closest one, while if refering to that noun makes the sentence non-sense, then worng.
Derivative of B). if logically it should refer to the further noun, while grammatically it has to refer to the closest one hence non-sense, then wrong

About C & D
actually D is not that confussing for that D actually suggests that 33% of the nuclear power in france are from Germany. The inadvertent repeat of using "energy" suggests that "this energy" is the same one as previous, thus misleading the concept.
