Affirming the consequent is an invalid form of conditional reasoning, where if P then Q, Q is observed, therefore P must be true. However, there may be multiple explanations for Q, and therefore it cannot be concluded that P is true based solely on the observation of Q. Modus ponens (A) and denial of consequent (B) are valid forms of reasoning, while affirming the antecedent (C) is a valid form of reasoning only in a mathematical context.
