Answer:
Letter D is the correct option.
Step-by-step explanation:
Faulty logic can be understood as a reason with imperfections and there are several types of it. Letter D can be explained as faulty logic because the first fact (people being selfish) is taken as the reason for not requiring service hours (selfish people don't want people to help other people). It could be understood as a false causality or an overgeneralization as long as the author does not present his information sources and the methodology used to express such a categoric answer. Also, this negative answer to the requirement may answer to more complex causes than just "selfish people".
