There is a verb 'might exacerbate' in non-underlined part of the sentence but that is not connected with a other verbal 'is' in the sentence properly. Drop A, D and E. Ideally we require another clause or some other connector that connects the 2 verbs properly - this is done in B & C only

B vs C

C - emphasis in on concern not on environmental groups because of passive structure. Secondly, it uses 'the offshore..' not present in the original sentence.

IMO B

This is a good explanation. Further, since we don't actually have a subject for "might exacerbate" in the non-underlined part and we know we have environmental groups concerned, we can predict that they'll be concerned something "might exacerbate."
