A) a fallacy
B) a tautology
C) equivalent to \[\tilde{\ }p\to q\]
D) equivalent to \[p\to \tilde{\ }q\]
Correct Answer: D
Solution :
[d] \[\tilde{\ }s\vee (\tilde{\ }r\wedge s)=(\tilde{\ }s\vee \tilde{\ }r)\wedge (\tilde{\ }s\vee s)\] \[=\tilde{\ }(\tilde{\ }s\wedge r)\wedge t\] \[=\tilde{\ }(s\wedge r)\] So, negation is \[s\wedge r\].
