Let 
and 
are two mathematical operators. If p 
(p 
q) is not a tautology, then 
and 
can be
A
and 
respectively
B
and 
respectively
C
and 
respectively
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
=> and A respectively
is false only if p is false and (p 
q) is false which is never possible simultaneously. Hence, 
is a tautology
is false only if p is true and (p 
g) is false which is never possible simultaneously. Hence, 
is a tautology
is false only if p is true & 
is false which is possible when p is true &q is false. Hence, 
is not a tautology
