7. The commission has directed advertisers to restrict the use of the word "natural" to foods that do not contain color or flavor additives, chemical preservatives, or nothing that has been synthesized.
(A) or nothing that has been
(B) or that has been
(C) and nothing that is
(D) or anything that has been
            
(E) and anything

(C) of greater economic development and invest
(D) of greater development economically and invest
(E) for greater economic development and the investment of
