In which type of fallacy does the conclusion not come from concrete evidence? Ad hominem
Non-sequitor

Ad hominem

Explanation:

 The ad hominem fallacy doesn't come from any concrete evidence, because, as stated in your lesson, it's literally an "argument against a person." It doesn't consider any facts on the real matter at hand, instead, it assumes the matter is bad just because a certain person is involved.
