In the context of logical fallacies, what does "tu quoque" imply?

The term "tu quoque," which translates from Latin as "you too," refers to a specific type of logical fallacy where an argument is rebutted by pointing out that the opponent should not be making that argument because they themselves do something they criticize. This fallacy highlights self-contradiction: instead of addressing the substance of the argument at hand, it shifts the focus to the opponent’s behavior, implying hypocrisy. Therefore, recognizing "tu quoque" as identifying self-contradiction in arguments correctly captures the nature of this fallacy. In contrast, the other options do not accurately reflect the essence of "tu quoque" and instead focus on different forms of reasoning or argumentation.
