I would not have selected E on test day (though OA is E) because of this statement "Yet the manufacturers have been spending an amount equal to 10 percent of their gross receipts". It is just not one company that is spending money; it is definitely a larger segment. Hence the criticism that "what is true for a group may not true for an individual" is not applicable (or at least that is what I thought).
Bottomline : My score is zero on this question.
