A) NO CHANGE B) brought up among C) broke out among D) broke out between

Before making any decisions, read the entire sentence and try to understand the context in which the word or phrase is being used. This will help in identifying the most appropriate option. The sentence is: "Growing protests and civil unrest ___ environmentalists and industrialists might soon escalate into a full-blown crisis." The different options are: A) NO CHANGE B) brought up among C) broke out among D) broke out between

Now that we have read the sentence, let's analyze each option and consider how it changes the meaning of the sentence: A) NO CHANGE - This means that the blank space should remain empty, resulting in a sentence that reads, "Growing protests and civil unrest _____ environmentalists and industrialists might soon escalate into a full-blown crisis." However, a phrase is missing, so this option doesn't make sense. B) brought up among - This phrase implies that the protests and civil unrest are being raised or discussed among environmentalists and industrialists. However, this option doesn't quite fit the context, as it doesn't convey a sense of conflict or disagreement. C) broke out among - This phrase suggests that the protests and civil unrest began within a single group, either the environmentalists or the industrialists. However, this option doesn't effectively convey the opposition between the two groups. D) broke out between - This phrase implies that the protests and civil unrest are taking place between the two groups, environmentalists, and industrialists, which fits the context of the sentence and indicates a conflict between them.

After analyzing each option, option D) "broke out between" is the best fit for the sentence, as it indicates a conflict between environmentalists and industrialists. So, the correct sentence should be: "Growing protests and civil unrest broke out between environmentalists and industrialists might soon escalate into a full-blown crisis."
