Hello there!

In this paragraph listed above, we can see how this lionfish would be very important to our ecosystem, and based on this, they are wanting to figure out ways to control it and to keep this animal toned down (in a sense).

In this paragraph, we would want to find a answer that would clarify that the lionfish would be able to continue to produce, and based on the options listed above, your answer would be actually option C.

We may never be able to completely remove the threat. 

This sentence above would indicate that sense this lionfish would not be removed what so ever, this would be that it would then not vanish, but continue to grow. And therefore, that would indeed be your answer.

Your  Option C : We may never be able to completely remove the threat. 

Iam sorry i do not know the answer
