A bit confused on this.

B & D can be eliminated for subject-verb agreement.
IMO "C" is parallel

I agree with C as well. Is the question stem grammatically correct in “What concern scientists”? Shouldn’t this be “What concerns scientists” as ‘risks’ are plural. In fact if it was singular shouldn’t it be “What is a concern to scientists”.

Eg.
I have a concern.
I have concerns.

Is "What concern scientists the most" correct? Shouldn't it be "What concerns"?

Because of concern I ended up selecting between B and D..."My concern is" and "my concerns are"

the sentence should have are because of the RISKS. So eliminate B and D
Now look for ||ism. Only C maintains that.

C is correct

I think you just have to take the cue from the subject (the noun clause "what concern...warming") where it uses the form "concern", that the subject is plural, and therefore "are" is the correct form of the working verb. Of course parallelism in the rest of the sentence has to be maintained so C should be the right answer.

I have concerns.

A little awkward, but I think "what" in that case is referring to a plural topic—"are the risks + list of several risks."

Correct me if I'm wrong, but if "what" weren't clarified, "what" should probably be assumed as singular. Because it is clarified as plural, you can say "What concern scientists."

Still say C, but thinking about this one again, I think the second part of the sentence (the answer choice) is actually the subject in this case. Flip the sentence around and you'll see that "are" is correct.

In this question, concern is acting as verb, and risks is plural so it should be concern not concerns. In your example "my concerns are" "my concerns" is acting as noun so to make this plural "concerns" is right one.

The subject of the original sentence is "what", which can be singular or plural depending on the
context. In this case, in the opening clause "what concern scientists", the plural verb "concern" follows
"what." Additionally, "what" serves as the subject of the main clause, "what . . . are the risks." If we
flip this around, we get "the risks are . . . what." The plural noun "risks" forms the complement of
"what." Thus, we have a situation where the verb of the what-clause ("concern") and the complement
of the main clause ("the risks") are both plural; thus, the verb of the main clause should also be plural.
The original verb "are" is therefore correct. However, the original sentence is incorrect because the
second half of the sentence is not structurally parallel. The first and third risks are introduced using the
word "that" while the second risk is not.

(A) This choice is incorrect as it repeats the original sentence.

(B) This choice incorrectly uses the singular verb "is" when the word "what" acts as a plural subject in
this context.

(C) CORRECT. The main clause uses the plural verb "are" and each of the three risks is introduced with the word "that", thereby creating a parallel structure.

(D) This choice incorrectly uses the singular verb "is" when the word "what" acts as a plural subject in this context. Additionally, the second half of the sentence is not structurally parallel. The first and third risks are introduced using the word "that" while the second risk is not.

(E) The three risks are not written in parallel form. The first risk is introduced by the preposition "of" (the risk of polar ice caps. . .). The preposition "of" is also implied in the second (the risk of seas . . .). However, the third risk is introduced with the preposition "that" (the risk that violent weather patterns . . .).

What concern scientists the most about global warming are the risks that the polar ice caps will melt, the seas will grow too warm to sustain marine life, and that violent weather patterns may result.

What is important here is the plural word - 'concern' hence the verb 'are' is correct here.

The next thing we should be looking for if the list is parallel and this parallel structure can be best established per below:

- are the risks:

----that the polar ice caps will melt
----that the seas will grow too warm to sustain marine life, and
----that violent weather patterns may result

Hence - Option C is Correct
