If the Boolean expression $\left( {p \oplus q} \right) \wedge \left( { \sim p\,\Theta\, q} \right)$ is equivalent to $p \wedge q$, where $ \oplus $ , $\Theta \in \left\{ { \wedge , \vee } \right\}$ , ,then the ordered pair $\left( { \oplus ,\Theta } \right)$ is
$\left( { \vee , \wedge } \right)$
$\left( { \vee , \vee } \right)$
$\left( { \wedge , \vee } \right)$
$\left( { \wedge , \wedge } \right)$
