The correct answer is: D. Neither I nor II is strong
Argument I is not strong because it does not provide any evidence that trapping wild animals is harmful. It simply states that trappers are making a lot of money, which does not necessarily mean that trapping is a bad thing. In fact, trapping can be a sustainable way to manage wildlife populations.
Argument II is not strong because it does not provide any evidence that bans on hunting and trapping are ineffective. It simply states that bans on hunting and trapping are not effective, which does not necessarily mean that they will not be effective in the case of trapping wild animals. In fact, there is evidence that bans on hunting and trapping can be effective in protecting wildlife populations.
Therefore, neither argument is strong.
