(C) $1$. The implication $p 	o (q \lor \sim r)$ is false only when $p$ is $T$ and $(q \lor \sim r)$ is $F$.$2$. For $(q \lor \sim r)$ to be $F$, both $q$ must be $F$ and $\sim r$ must be $F$. Thus, $q = F$ and $r = T$.$3$. Now, evaluate $(p \leftrightarrow q) \land r$: Since $p = T, q = F, r = T$, we have $(T \leftrightarrow F) \land T = F \land T = F$.$4$. Evaluate $\sim p 	o \sim q$: Since $p = T, q = F$, we have $\sim T 	o \sim F = F 	o T = T$.$5$. Therefore, the truth values are $F, T$.

If $p \to (q \lor \sim r)$ is false, then the truth values of $(p \leftrightarrow q) \land r$ and $\sim p \to \sim q$ are :
