Question:
Which of the following expression is a tautology?
Which of the following expression is a tautology?
Show Hint
Use truth tables to evaluate expressions and verify tautologies — always result in “True”.
Updated On: Jun 5, 2025
- \(p \land \text{False}\)
- \(p \land \text{True}\)
- \(p \lor \text{False}\)
- \(p \lor \text{True}\)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A tautology is a proposition that is always true, regardless of the truth value of its components. \(p \lor \text{True} = \text{True}\) for any \(p\), hence it is a tautology.
