A) Fear appeals to the desire to be safe. To clarify, appeal to fear means presenting alternatives, one of which causes fear in order to force the person to choose what you would like them to choose.
B) False Dichotomy gives two choices, one of which is not truly an option. In false dichotomy, the alternatives do not exclude each other. They overlap, which means the person isn't really presented with a real opportunity to choose.
C) Slippery slope claims that one action leads to a series of undesirable events. This fallacy suggests that an insignificant first event might lead to another event, that might lead to yet another one and so on until, ultimately, a grand or disastrous event would happen in consequence of that first, small one.
D) Popularity claims something is true because most people agree. This fallacy basically states that, if everyone is doing it, then it's because it is the right thing to be done.
E) Post Hoc incorrectly assumes that one event causes another. This fallacy assumes that temporal succession establishes a connection between events. That is, if this event came after that one, it must be its consequence.
