This sentence compares percentages and uses the prepositional phrases in France and in Germany to distinguish the percentage of energy in each country coming from nuclear power. This information is most efficiently and clearly presented in two clauses joined by the conjunction whereas, which signifies a difference between the situations in the two countries. Each clause must identify what the percentage refers to—that is, the portion of the respective country's energy that comes from nuclear power.
AWhile is somewhat ambiguous, since it might indicate simultaneity rather than contrast; the referent of it is ambiguous, raising questions about just what two things are being compared.
BThis sentence compares 75percent to Germany; it is not clear what 33percent refers to.
CCorrect. The two clauses joined by whereas indicate clearly that the comparison is between the different percentages of energy coming from nuclear power.
DThe use of the definite article the makes it seem as though the energy being referred to in this part of the sentence is that of France.
