Nutritionist: Your company's fruit-processing technologies add unacceptable amounts of copper to the orange juice you sell. Because copper blocks the absorption of Vitamin C, your advertising campaign claiming that your juice is a good source of Vitamin C is faulty and should be removed.

Juice Manufacturer: Some amount of copper is necessary for optimal health. Recent studies have shown that as many as 25 percent of Americans do not get enough copper in their diets; therefore, the benefits of the copper that our process adds to the juice outweigh the costs of any Vitamin C that it may block.

The juice manufacturer's response is flawed as a refutation of the nutritionist's argument because it

A:relies on the unfounded assumption that copper may be as good for health as Vitamin C.

B:does not address the issue of whether sufficient amounts of copper are present to invalidate its advertising claims.

C:fails to describe how much Vitamin C the juice company adds to each bottle, as stated in the advertising campaign, and how much is blocked from absorption by copper.

D:addresses the nutritionist`s argument in general terms, rather than in terms of the health of individuals.

E:shows that the nutritionist`s evidence about copper is irrelevant but fails to demonstrate any flaws in the nutritionist`s assumptions.
