A
True if the truth values of $p,q,r$ are $T,F,T$ respectively
B
False if the truth values of $p,q,r$ are $T,F,T$ respectively
C
False if the truth values of $p,q,r$ are $T,F,F$ respectively
D
True if the truth values of $p,q,r$ are $F,T,F$ respectively
Solution:
$\left(\sim T \lor F\right)\land \sim T\Rightarrow T$
$\left(F \lor F\right)\land F\Rightarrow T$
$F\lor F \rightarrow T$
$F \rightarrow T$ which is $T$
