A) \[p\wedge q\] is true
B) \[p\vee \tilde{\ }q\] is true
C) \[q\wedge p\] is true
D) \[p\Rightarrow q\] is true
Correct Answer: D
Solution :
[d] When p is false and q is true, then \[p\wedge q\] is false, \[p\vee \tilde{\ }q\] is false. (\[\because \] both p and \[\tilde{\ }q\] are false) and \[q\Rightarrow p\] is also false, only \[p\Rightarrow q\] is true.
