Vedclass · Answer

(D) tautology is a statement that is true for all possible truth values of its components. We evaluate the truth table for the expression $(p \wedge q)$ $\rightarrow (p$ $\rightarrow q)$:      $p$    $q$    $p \wedge q$    $p \rightarrow q$    $(p \wedge q)$ $\rightarrow (p$ $\rightarrow q)$        $T$    $T$    $T$    $T$    $T$        $T$    $F$    $F$    $F$    $T$        $F$    $T$    $F$    $T$    $T$        $F$    $F$    $F$    $T$    $T$  Since the final column contains only $T$ (True),the expression $(p \wedge q)$ $\rightarrow (p$ $\rightarrow q)$ is a tautology.
