(C) Given truth values: $p = T, q = F, r = T$.Step $1$: Evaluate option $(A)$: $[F \land (T 	o F)] 	o T = [F \land F] 	o T = F 	o T = T$.Step $2$: Evaluate option $(B)$: $(T \land F) 	o (F \lor \sim T) = F 	o (F \lor F) = F 	o F = T$.Step $3$: Evaluate option $(C)$: $[(\sim T \lor F) \land \sim T] \leftrightarrow T = [(F \lor F) \land F] \leftrightarrow T = [F \land F] \leftrightarrow T = F \leftrightarrow T = F$.Step $4$: Evaluate option $(D)$: $(T \land F) \lor (\sim F \lor T) = F \lor (T \lor T) = F \lor T = T$.Since option $(C)$ results in $F$, it is not a true statement.

If $p, q, r$ are simple propositions with truth values $T, F, T$ respectively, then which of the following is not a true statement?
