Although perioral dermatitis rashes are believed to be caused by reactions to Sodium Laurel Sulfate (SLS) found in shampoos and other personal care products, instructing patients to eliminate all products with SLS frequently does not stop the perioral dermatitis. Obviously, some other cause of perioral dermatitis besides reactions to SLS must exist.
Which of the following, if true, would most seriously weakens the conclusion above?
A. Many personal care products elicit an allergic skin response only after several days, making it very difficult to observe links between specific products patients use and the perioral dermatitis they develop.
B. Skin allergies affect many people who never develop the symptom of perioral dermatitis.
C. Many patients report that the personal care products that cause them perioral dermatitis are among the products they most enjoy using.
D. Very few patients have allergic skin reactions as children and then live rash-free adult lives once they have eliminated products to which they have been demonstrated to be allergic.
E. Very rarely do personal care products cause patients to suffer a symptom more severe than that of perioral dermatitis rashes.

The argument says that perioral dermatitis rashes are believed to be caused by reactions to Sodium Laurel Sulfate (SLS) found in shampoos and other personal care products. But even when patients stop using products with SLS, perioral dermatitis rashes do not go away. So there must be something else causing perioral dermatitis rashes.
To weaken we need to show perioral dermatitis rashes are indeed caused by products containing SLS.
A) Says that allergic reactions appear several days after use and and hence there is no link between products containing SLS and perioral dermatitis rashes but weakly also says the rashes may be caused by products containing SLS - Keep this choice for now.
B)Very strong - throw
C)We not concerned with patients happiness - throw
D)We not concerned with what happened when patients were children - throw
E)We not concerned with more severe symptoms - throw
