Certain synthetically produced foods may lack nutritional value if fre

(BCD) reason cannot be exposed to pesticides;
(E) implies flavonoids are not discovered in other plants.

Ans (A)

The right answer is A.

Meaning: Certain synthetically produced foods may lack nutritional value. How? If [the foods are] frequently exposed to pesticides. One reason[for the lack of nutritional value] is indicated by the discovery that there are far fewer disease-fighting micronutrients. These micronutrients are called flavonoids. The micronutrients are far fewer X: in plants that are chemically treated to prevent insect attacks than Y: in plants that are allowed to repel insects naturally.

The original sentence is correct. There is a comparison between X: the micronutrients in plants that are chemically treated to prevent insect attacks and Y: the micronutrients in plants that are allowed to repel insects naturally. X and Y are both prepositional phrases and rightly expressed in parallel to each other.

B and C can be eliminated because they have dangling modifiers. One reason cannot be frequently exposed to pesticides.

In D, there is no need for the word that in front of certain synthetically produced foods may lack nutritional value. The introduction of that implies if frequently exposed to pesticides illogically modifies the main clause the discovery is indicative of one reason and this is unintended. D can be eliminated based on this.

E is run-on. There is no conjunction whatsoever to connect two main clauses: the discovery indicates one reason and certain synthetically produced foods may lack nutritional value if frequently exposed to pesticides. E can be eliminated.

Certain synthetically produced foods may lack nutritional value if frequently exposed to pesticides; one reason is indicated by the discovery that there are far fewer disease-fighting micronutrients, called flavonoids, in plants that are chemically treated to prevent insect attacks than in plants that are allowed to repel insects naturally.

A. Certain synthetically produced foods may lack nutritional value if frequently exposed to pesticides; one reason is indicated by the discovery that there are far fewer disease-fighting micronutrients, called flavonoids, in plants that are chemically treated to prevent insect attacks than in plants that are allowed to repel insects naturally.

B. If frequently exposed to pesticides, one reason that certain synthetically produced foods may lack nutritional value is indicated by the discovery that there are far fewer disease-fighting micronutrients, called flavonoids, in plants that are chemically treated to prevent insect attacks than in plants that are allowed to repel insects naturally.

C. If frequently exposed to pesticides, one reason certain synthetically produced foods may lack nutritional value is indicated by the discovery that far fewer disease-fighting micronutrients, called flavonoids, are found in plants that are chemically treated to prevent insect attacks than those that are allowed to repel insects naturally .

D. The discovery that there are far fewer disease-fighting micronutrients, called flavonoids, in plants that are chemically treated to prevent insect attacks than in plants that are allowed to repel insects naturally is indicative of one reason, if frequently exposed to pesticides, that certain synthetically produced foods may lack nutritional value.

E. The discovery of disease-fighting micronutrients, called flavonoids, in plants with chemical treatments to prevent insect attacks than in those that are allowed to repel insects naturally indicates one reason certain synthetically produced foods may lack nutritional value if frequently exposed to pesticides.

It's a clear A because other lacks in structure, wordy.
