The correct answer for:

There is generally agreement that feral swine are unwelcome

Is:

D)like the Asian carp that are threatening to invade Lake Michigan, but far larger, more vicious, and mounted on four legs

Explanation:

The reason behind this answer is the use of the verbs and the order of the words and their meaning. First of all the difference between the use of like and such. IS that Like resembles a similar object that the one we are talking about initially. While such is a concept used to provide an example about subgroups inside the initial category, and feral swine are not a subspecies of the Asian carp. So we need to look for a proper answer. We end up with c and d, Being differentiated by their descriptions of the animals. In c) we understand that there is an executive to be verb on the final part of the description. While D) options follow a continuation of it. Making it the correct answer.
