Consumer advocate: Even if one can of fruit or vegetables weighs more than another, the heavier can does not necessarily contain more food. Canned fruits and vegetables are typically packed in water, which can make up more than half the total weight of the can's contents. And nothing stops unscrupulous canning companies from including more water per can than others include.
Which one of the following most accurately expresses the conclusion drawn in the consumer advocate 's argument?
(A) The heavier of two cans of fruit or vegetables does not necessarily contain more food than the lighter of the two cans contains.
(B) The weight of the water in a can of fruit or vegetables can be more than half the total weight of the can's contents.
(C) Nothing stops unscrupulous canning companies from including more water per can than others include.
(D) Some canning companies include less food in cans of a given weight than others include.
(E) The heavier of two cans of fruits or vegetables may include more water than the lighter of the two cans contains.

A is just the exact opening sentence (re-worded a bit).
B is the exact fact stated in the second sentence.
C is again just the concluding sentence of the argument.
D is out of context as nothing in the argument says anything about the relevance of 'given weight'
E is again similar to A, but just from another perspective
And in case anyone is concerned about how to tackle such a question, you can relax as such a question will never come in the GMAT.
