A) \[\tilde{\ }(p\vee \tilde{\ }q)\to \tilde{\ }r\]
B) \[(\tilde{\ }p\wedge q)\to \tilde{\ }r\]
C) \[(\tilde{\ }p\vee q)\to \tilde{\ }r\]
D) None of these
Correct Answer: C
Solution :
The inverse of the proposition \[(p\wedge \tilde{\ }q)\to r\]is \[\tilde{\ }(p\wedge \tilde{\ }q)\to \tilde{\ }r\] \[\equiv \tilde{\ }p\vee \tilde{\ }(\tilde{\ }q)\to \tilde{\ }r\] \[\equiv \,\tilde{\ }p\vee q\to \tilde{\ }r\]
