Official Explanation
In the original sentence, the antecedent of that result is unclear. Is it DNA strands or damage to those strands that result from the deployment of enzymes? Also, the use of the noun clause man-made toxins’ invading in a prepositional phrase here is somewhat awkward, albeit grammatically correct.
Choice (B) improperly uses that instead of which. Also, it is unclear what “resulting” refers to here—DNA strands or damage to the DNA strands.
Choice (C) improves on the awkward use of a noun clause in the first part of the original sentence. The infinitive to rebuild and the phrase as a result clarify the meaning of the second part of the sentence. In spite of its use of the passive voice (enzymes are deployed), choice (C) is the best version.
The correct answer is (C).
