Cafereria patron The apples sold in this cafeteria are greasy. The cashier told me that the apples are in that condition when they are delivered to the cafeteria and that the cafeteria does not wash the apples it sells. Most fruit is sprayed with dangerous pesticides before it is harvested, and is dangerous until it is washed. Clearly, the cafeteria is selling pesticide-covered fruit thereby endangering its patrons.
Which one of the following is an assumption on which the argument depends?
(A) The apples that the cafeteria sells are not thoroughly washed after harvest but before reaching the cafeteria
(B) Most pesticides that are sprayed on fruit before harvest leave a greasy residue on the fruit
(C) Many of the cafeteria's patrons are unaware that the cafeteria does not wash the apples it sells.

(D) Only pesticides that leave a greasy residue on fruit can be washed off
(E) Fruits other than apples also arrive at the cafeteria in a greasy condition
