The Boolean expression

$$\left( {p \wedge \sim q} \right) \vee q \vee \left( { \sim p \wedge q} \right)$$ is equivalent to :

The negation of $$ \sim s \vee \left( { \sim r \wedge s} \right)$$ is equivalent to :

The statement $$ \sim \left( {p \leftrightarrow \sim q} \right)$$ is :

Consider :
Statement − I : $$\left( {p \wedge \sim q} \right) \wedge \left( { \sim p \wedge q} \right)$$ is a fallacy.
Statement − II :$$\left( {p \to q} \right) \leftrightarrow \left( { \sim q \to \sim p} \right)$$ is a tautology.
