MCQ

Given below are four statements along with their respective duals. Which dual statement is not correct?

A
$(p \vee q) \wedge(r \vee s),(p \wedge q) \vee(r \wedge s)$
B
$(p \vee \sim q) \wedge(\sim p),(p \wedge \sim q) \vee(\sim p)$
C
$(p \wedge q) \vee r,(p \vee q) \wedge r$
✓
$(p \vee q) \vee s,(p \wedge q) \vee s$

✓

Answer

Correct option: D.

$(p \vee q) \vee s,(p \wedge q) \vee s$

(D)
Dual of ${ }^{\prime}(p \vee q) \vee{ }^{\prime}$ is ${ }^{\prime}(p \wedge q) \wedge s^{\prime}$.
