Farmer: Though illnesses caused by commercial produce consumption are usually attributed to the use of pesticides on the affected plants, the reality is that pesticides are not usually to blame. Since pesticides are only dangerous when consumed in large quantities, most people who experience stomach pains as a result of eating some sort of fruit or vegetable are actually suffering as a result of their food allergies, and would have become just as ill from pesticide-free produce.

Which of the following, if true, best supports the farmer's argument?
(A) People who experience stomach pains from ingesting pesticides generally suffer from no more food allergies than do people who do not experience such symptoms.
(B) Numerous tests have shown that beef derived from livestock raised on pesticide-exposed feed is safe for human consumption.
(C) Pesticide allergies have been known to cause symptoms similar to those arising from food allergies.
(D) Stomach pain and other food allergy symptoms are not associated with illnesses caused by pesticides, which are statistically rare and take longer to manifest.
(E) Many fruits and vegetables trap pesticide residue in the porous cell membranes just under the skin.
