Q. If $p:4$ an even prime number $q:6$ is a divisor of 12 and $r:$the HCF of 4 and 6 is 2, then which one of the following is true?
A) $(p \vee q)$
B) $(p \vee q) \land \sim r$
C) $\sim(q \land r) \vee p$
D) $\sim p \vee (q \land r)$
Explanation
(d)
$\therefore p:4$ is an even prime number.
$q:6$ is a divisor of 12
And $r:$ the HCF of 4 and 6 is 2
$\therefore\ \ \ \sim p \vee (q \land r)$ is true.
