Hi, we are evaluating the argument that since the product was tested by a lab, consumers can safely assume that the product is safe. This seems fishy: anything can be tested, but what are the results? If the lab said that these are wildly unsafe that would obliterate the argument.
This is a good match for C. The issue with B is that it isn't relevant to the argument. The argument has nothing to do with whether consumers do or do not consider safety, the argument is that since safety is important, they should choose us.
