Correct answer is (c) (∼ p ∧ q ) ∧(∼ q )

Q. Which of the following statement is a contradiction-

$(\sim p \lor \sim q) \lor (p \lor \sim q)$

$(p \to q) \lor (p \land \sim q)$

$(\sim p \land q) \land (\sim q)$

$(\sim p \land q) \lor (\sim q)$

Correct answer is (c) $(\sim p \land q) \land (\sim q)$

Q. Which of the following statement is a contradiction-

(∼p∨∼q)∨(p∨∼q)

(p→q)∨(p∧∼q)

(∼p∧q)∧(∼q)

(∼p∧q)∨(∼q)

Correct answer is (c) (∼p∧q)∧(∼q)

$(\sim p \lor \sim q) \lor (p \lor \sim q)$

$(p \to q) \lor (p \land \sim q)$

$(\sim p \land q) \land (\sim q)$

$(\sim p \land q) \lor (\sim q)$

Correct answer is (c) $(\sim p \land q) \land (\sim q)$
