Logical Equivalence And Truth Tables

- **A** corresponds to **I** because **Biconditional elimination** refers to eliminating a biconditional expression and converting it into two conditional expressions. The equivalence is . - **B** corresponds to **II** because **De Morgan's law** deals with negating and distributing logical operations such as conjunction and disjunction. - **C** corresponds to **III** because **Distributivity of over ** states that a logical or ( ) distributes over a logical and ( ), as shown in the equivalence. - **D** corresponds to **IV** because **Contraposition** involves flipping and negating both parts of an implication. Step 2: Conclusion. The correct match is **A - I, B - II, C - III, D - IV**.
