The answer is most likely C. There is no reference in the text about insects, no information related to Puerto Rico or Florida, and while only the male ones are specified which could make you think the answer is the one related to female ones there lacks anything saying that they aren't also a problem. It is also known fact that the coqui in Hawaii lack having natural predators and there is emphasis on them being the ones endangering others which should further prove C is the answer. Good luck!
