1) Consider statement I (p∧∼q)∧(∼p∧q) is a fallacy. Statement II (p→q)↔(∼q→∼p) is a tautology A) Statement I is true, statement II is true; statement II is a correct explanation for statement I B) Statement I is true, statement II is true; statement II is not a correct explanation for statement I C) statement I is true ; Statement II is false D) statement I is false ; Statement II is true Answer: Option BExplanation:statement II (p→q)↔(∼q→∼p) ≡(p→q)↔(p→q) which is always true, so statement II is true. Statement I (p∧∼q)∧(∼p∧q) ≡p∧∼q∧∼p∧q ≡p∧∼p∧∼q∧q ≡f∧f≡f Hence, it is a fallacy statement So, statement I is true
