Invasive species are the one that are naturally not found in a habitat and exert negative impacts on the native species of that habitat. The beetle enters the New York's Central Park from a foreign country, that is, it is not native to the central park. Since it causes adverse impacts on a native tree species of the park, it is an example of "invasive species".
"Invasive species" is the one among the following choices given in the question that the beetle is an example of. The correct option among all the options that are given in the question is the second option or option "b". I hope that this is the answer that has actually come to your desired help.
