Answer is D. The main point of mayor is , in order to boost the economy he wants to kill the sharks. But if we carefully notice, tourism is only second to fishing industry in bringing revenues. So if we can find any choice that would effect the fishing industry when we kill the sharks would be the right choice. And D does that.
