Answer: D

Explanation:

The original underlined portion is incorrect because of the improper use of the “not only…but also…” structure. Only choice “understand global warming but also to prevent it” and choice “understand global warming but also to prevent its growth” use this structure, but choice “understand global warming but also to prevent its growth” accurately adds “to prevent its growth.” The sentence began by discussing growth because global warming is a dynamic problem that has not just stagnated; it continually has changed. Choice “understand global warming but also to prevent its growth” corrects the structure and also uses the proper possessive form of it (i.e. its).
