Which fallacy diverts attention by introducing an irrelevant issue?

The Red Herring Fallacy is the correct choice because it specifically refers to a tactic where an irrelevant topic is introduced in order to divert attention from the original issue being discussed. This strategy often leads the audience away from the core argument or question and shifts the focus onto something that may seem related but ultimately distracts from the critical point at hand.

For instance, in a debate about climate change, someone might suddenly start discussing the economic benefits of fossil fuels, which is not directly relevant to the scientific arguments regarding climate change. This misdirection creates confusion and can prevent a constructive discussion about the primary issue.

In contrast, the other fallacies listed do not operate in this exact manner. Tu Quoque generally focuses on hypocrisy as a defense rather than diverting attention. Slippery Slope involves arguing that a particular action will lead to a series of negative consequences, which again addresses the original argument but in a flawed manner. Special Pleading involves applying rules or standards to one side while ignoring the same standards for another, thus it does not create a diversion but rather manipulates criteria for judgment.
