(A) people in France consume fatty foods at a rate comparable to the United States, their
1) error of comparison: "
a rate comparable to the United States". "Rate" is being compared with "the US".
2) Redundancy:
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.Here, "their" refers to "people in France", Hence the sentence says that

2) Foods don't have "rates"
(E) the rate of people consuming fatty foods is about the same in France and the United States, the
1) The same problems as in (D)
