(D) tautology is a statement that is true for all possible truth values of its components.We construct the truth table for the given options:| $p$ | $q$ | $\sim p$ | $\sim q$ | $\sim p \vee \sim q$ | $p \vee \sim q$ | $(\sim p \vee \sim q) \vee (p \vee \sim q)$ ||---|---|---|---|---|---|---|| $T$ | $T$ | $F$ | $F$ | $F$ | $T$ | $T$ || $T$ | $F$ | $F$ | $T$ | $T$ | $T$ | $T$ || $F$ | $T$ | $T$ | $F$ | $T$ | $F$ | $T$ || $F$ | $F$ | $T$ | $T$ | $T$ | $T$ | $T$ |As seen in the final column,the statement $(\sim p \vee \sim q) \vee (p \vee \sim q)$ is true for all combinations of $p$ and $q$.Therefore,it is a tautology.
