The correct Answer is:
To solve the question, we need to determine the truth value of the statement: "Always true statement is called contradiction." ### Step-by-Step Solution: 1. **Understanding the Terms**: - An "always true statement" is known as a **tautology**. This means that no matter what values or conditions are applied, the statement remains true. - A **contradiction**, on the other hand, is a statement that is always false regardless of the conditions or values. 2. **Analyzing the Given Statement**: - The statement claims that an "always true statement" is called a contradiction. - We need to check if this claim aligns with the definitions of tautology and contradiction. 3. **Comparing Definitions**: - Since we know that an always true statement is a tautology, and a contradiction is defined as a statement that is always false, we can conclude that the statement provided in the question is incorrect. 4. **Conclusion**: - Since the statement "Always true statement is called contradiction" does not hold true based on the definitions, we conclude that the statement is false. 5. **Final Answer**: - Therefore, we write 'F' for False.
