    A)                 F, F                                        

    B)                                        T, T

    C)                                        T, F                        

    D)                                        F, T                

    Correct Answer: C

    Solution :

                    \[p\to (\tilde{\ }p\vee q)\]has truth value F. It means \[p\to (\tilde{\ }p\vee q)\]is false. It means p is true and \[\tilde{\ }p\vee q\]is false. \[\Rightarrow \]is time and both \[\tilde{\ }p\] and q are false. \[\Rightarrow \]is true and q is false.
