    A) \[(\sim p\wedge \sim q)\]\[\Rightarrow \] \[(r\wedge s)\]

    B) \[\sim (p\wedge q)\]\[\Rightarrow \]\[(r\wedge s)\]

    C) \[\sim (p\vee q)\]\[\Rightarrow \]\[(r\vee s)\]

    D) None of these

    Correct Answer: B

    Solution :

    Correct result is           \[\left( \sim p\vee \sim q \right)\]  \[\Rightarrow \]   \[\left( r\wedge s \right)\] or       \[\sim \left( p\wedge q \right)\]  \[\Rightarrow \]  \[r\wedge s\]
