Question

If "All odd numbers are primes and the sum of three angles in a triangle is ${190}^{\circ }$", then "All odd numbers are primes or the sum of the angles in a triangle is ${190}^{\circ }$" is a

• A. tautology
• B. contradiction
• C. contingency
• D. not a statement

Answer 1

The correct option is A tautology

Both the statements are false as all odd numbers are primes and the sum of three angles of a triangle is not ${190}^o$
A tautology is a statement that is always true. And Two false statements make a True statement in a Tautology.
