Answer:
The correct answer is option b.Ad hominem.
Step-by-step explanation:
The ad hominem fallacy is characterized by the attempt to discredit those who are defending their position by pointing out something negative about them.
Let's see how it works with the example given.
- X claims that Gracie is the worst class president ever.
- It is questioned that she does not even know how to dance.
- Therefore it is questioned that Gracie is the worst president class ever.
That would be the circuit that runs through an ad hominem fallacy, and which leads us to say that it is the correct answer.
