I believe that the most fitting answer for this question would be D., "emotional." This statement does not bring up any evidence or facts; therefore, it is not a logical approach. It does not bring up questions of right and wrong, so it is not an ethical approach. It also does not command authority, so it does not take an authoritative approach. Therefore, you only have one answer left. In addition, it appeals to the emotions by making you wonder about your child's safety. Hope this helps.
