Answer 2

Answer:

Option (C) is correct

Step-by-step explanation:

A statement pattern having truth value always F, irrespective of the truth values of its component statement is called a contradiction. A statement pattern having a truth value always T irrespective of the truth values of its component statement is called a tautology

p      ~p      (p V ~p)  

T       F             T

F      T              T



therefore, truth value of (p V ~p)  is always T, it is tautology.
